In the Windows operating system, each file type has its own extension... In some distributions, the display of extensions is disabled by default, which is not liked by all users. Enabling the display of extensions significantly improves the usability of your computer.
Instructions
The presence of extensions allows the user to judge the purpose of this or that. Executable files can have extension".Exe", ".com" or ".bat", text - ".txt", ".rtf" or ".doc", photos - ".jpg" or "jpeg", pictures - ".bmp", Internet files - ".htm", ".html", ".mht", media files - ".mov", ".avi", ".mpeg", etc. etc. The lack of display of extensions in many cases interferes with normal work with file mi - for example, when renaming them, so users usually try to enable this option.

Useful advice
Be careful when specifying a new extension, because if you make even the slightest mistake, the file may not be read by the program.
The file name consists of the full path to it on the hard drive, personal name and extension, usually indicated after the dot sign. If you have somehow removed the extension, then the operating system cannot automatically recognize the type of document and run it for execution in the corresponding program. The first step is to find out what type of file it belongs to.
You will need
- - computer;
- - TrID, FileInfo, File Analyzer programs;
- - the Internet.
Instructions
Download and install one of the TrID file analysis programs, FileInfo, File Analyzer and others. You can find it on the software website softodrom.ru or soft.ru. Use the program's features to find out the file type. If you are using TrID, it will display information about the possible file type as a percentage.
View the detailed binary data content in normal. At the beginning is the file signature - a special set of characters with information about the document. For example, for a RAR archive, the signature contains Rar characters. You can find out in detail the correspondence of signatures to file types via the Internet. You can also find out the extension of the document using the standard tools of the operating system. To do this, right-click on the file and select "Properties". A window will appear in front of you, in which all the relevant information will be presented.
Use -file recognition services. It is possible to check their type directly on the Internet with the same TrID program. Having found out the file type, add its full extension, simply changing the name of a specific document. Click on the file with the right mouse button and select "Rename" from the menu. Enter the extension without forgetting the dot sign.
Don't just delete it. You will easily forget the type of document, and the operating system will not automatically recognize the data and will not select the program to run. Take a close look at the extension of each file that is on your personal computer. In general, we can say that it is not so difficult to return the extension to any document, the main thing is to have the appropriate software.

Typically editing an extension file should reflect the change in the recording format of the information it contains. And such intervention in the file structure is most often carried out using specialized applications that change extension... But the cases when the user has to fix the extension on his own are still not so rare.
Instructions
The easiest way to change the file extension is to use a program specifically designed for working with files. There are many ways to open it in Windows OS - for example, right-click the "Start" button and in the pop-up list of commands select the line "open explorer".
In the left column of the file manager interface, select the disk where the rename object is located, and then, sequentially expanding the folders in the same left column, go to the directory containing the file.
If the extension of the desired object is not displayed in the file manager, then open the "Organize" drop-down list above the left column of Explorer and select the "Folder and search options" line. If your OS version does not have this list, then open the "Tools" section in the menu and select the "Folder Options" item. In both cases, the same window will open, in which you need a list of parameters on the "View" tab - find the line "Hide extensions for registered file types" in it. Uncheck this line and click OK.
Right-clicking the required file, select the "rename" command, go to the end of the name (press the End button) and correct the extension. Pressing the Enter key will commit the changed file name.
The same operation can be done on the command line, even if the display of the file extension is disabled in the Windows settings. The command line simulator window is invoked through the program launch dialog - press the Win and R keys simultaneously to open this dialog. Then type cmd, press Enter and a command prompt terminal will open.
Use the rename command or its shorthand ren to rename. This command requires the full path and name of the edited object, as well as the name of the file with the new extension (for the second parameter, the full path is not required). For example, if a file named someFile.doc is placed in the text folder of the root directory of drive F, then to change its extension from doc to txt, enter the following command: ren F: extsomeFile.doc someFile.txt and press the Enter key.

A type file is an internal data layout that differs from file to file. For example, for video files, the extension avi is one type, mkv is another, and mov is a third. Each of these standards has certain properties and characteristics. It so happens that you need to play the recording on some device that supports only avi-video. In this case, you need to convert the file from one type to another using a special program.
Instructions
Download a utility for converting video files, such as Any Video Converter. It is a free and handy tool for working with a very large list of video standards and types. Alternatively, you can use Total Video Converter or Format Factory. These programs can also change the video file type to avi.
Follow the link to the AVC developer site - http://www.any-video-converter.com/products/for_video_free/ or to any software portal on the Internet, for example www.softportal.ru or www.softodrom.ru, if you prefer another program. Click the Download or Download button and download the installation file.
Install data conversion software. To do this, find the installation file that you downloaded in the downloads folder of your browser. This is usually the My Documents Downloads folder, but other options are possible. Double-click the program installation and answer the wizard's questions. When it's over, you will have a shortcut on your desktop to launch the program.
Open Any Video Converter. Double click on the shortcut with the left mouse button or locate the folder in the Start menu, All Programs submenu. Click the "Add Video" button located in the upper left part of the window. Select the file you want to change. The video title and its parameters will appear in the main part of the window.
Select the line "Custom AVI" from the drop-down menu on the right side of the program, right above the video viewing window. At the bottom, under the viewing area, select encoding options. To do this, scroll through the list of possible settings, left-click on the desired line and select the appropriate option. For example, we recommend that you set the Video Resolution to Original so that the aspect ratio of the image is not changed. Also set the Frame Rate to AUTO.
The file retains a mention of this program. To change the summary, you need the ExifCleaner program. Find it on the Internet, download, open the image to be processed in it. Select the line with it, data about the photo will appear on the right side of the program window. Click on the Clean Setup button to mark the lines to be deleted. Then click Quick Clean - all selected data will be deleted.
If you need to not just delete, but replace photo data, use the ASDSee program. It has rich capabilities for working with images, and can change data from the summary of the file. You can download the 30-day version of the program: http://www.softportal.com/software-51-acdsee.html.
The Quick EXIF Editor is very good at editing summary image files. Its only drawback is its awkward interface. Download and install the program, run it. A small window will appear in front of you. Click the Open button and select the file you want. A drop-down list in the very center of the program will display the metadata.
2. Displaying file extensions can help you protect your computer from viruses. If you want to download an archive or a text document from the Internet, and a file with the .exe extension, denoting a program, has been downloaded to your computer, it is better to refuse to run this file, usually in this way cybercriminals force gullible users to install unnecessary programs and infect the computer with viruses.
Using standard Windows tools, you can change only some of the properties of files, for example, allow editing and deletion. To change the creation date, you have to use third-party programs or non-standard Windows tricks.
How to hide a file
Using standard Windows tools, you can hide the file you have created from viewing and prohibit its editing. To do this, right-click on its icon, select the "Properties" command, and in the "General" tab of the properties window, check the "Read-only" and "Hidden" attributes. Then go to the "Tools" menu and check the "Folder Options" item. In the "View" tab, find the item "Hidden folders and files" in the list of additional options and set it to "Do not show". Click OK to confirm. To restore the file's visibility, uncheck the Hidden attribute.
How to change file properties
You can change only some of the data in the file properties. If you have Windows XP, in the Properties window go to the Summary tab and click Advanced. Click in the "Value" section next to the property you want to change. If editing is allowed, an empty box appears with a frame around it.
To change the properties of a file in Windows 7 in the properties window go to the "Details" tab and proceed as described above.
How to change the creation date of a file
To find out the date the file was created, right-click on its icon and select the "Properties" command. The General tab displays basic information about the file, including the creation date. You will not be able to change this parameter using standard Windows tools, but you can use non-standard techniques. Double click on the clock in the tray (lower right corner of the screen) and set the date and time to which you want to change the real data of the file.
Open the file with a suitable editor (Word is suitable for text files, Paint or Photoshop for graphic files) and save it under your own name. Now the file properties will reflect the creation date you need.
You can use third-party programs to change file attributes, such as the Total Commander file manager. Launch TC and find the file you want to change in File Explorer.
In the "Files" menu, click the "Change Attributes" item and in the new window, check the box next to the "Change Date / Time" item. Then check the box next to "Use plugins". The "Plugin" field should be tc. In the "Property" field, open the drop-down list and select the "Creation date" item. In the "Value" field, enter the desired date and click OK.
For the likelihood of the adjustment, click "Add Attribute" and select "Modification Date" in the list of properties. Enter a date later than the creation date.
In the same window, you can prohibit editing the file and make it hidden. To do this, check the boxes "Read only" and "Hidden".
The need to change the file extension occurs when the wrong format name was mistakenly assigned to it initially or during saving. In addition, there are cases where items with different extensions are essentially the same format type (for example, RAR and CBR). And in order to open them in a specific program, you can simply change it. Let's see how to complete the specified task in Windows 7.
It is important to understand that simply changing the extension does not change the type or structure of the file. For example, if you change the filename extension from doc to xls in a document, it will not automatically become an Excel table. To do this, you need to carry out the conversion procedure. In this article, we will consider various ways to change the format name. This can be done both using the built-in Windows tools and using third-party software.
Method 1: Total Commander
First of all, let's consider an example of changing the name of the object format using third-party applications. Almost any file manager can handle this task. The most popular of these is undoubtedly.
Using Total Commander, you can perform batch renaming.
- First of all, you should select those elements that you want to rename. If you need to rename all the files in this directory, then we stand on any of them and use the combination Ctrl + A or Ctrl + Num +... Also, you can go to the menu by item "Selection" and select from the list "Select all".
If you need to change the name of the file type for all objects with a specific extension in this folder, then in this case, after selecting the item, go through the menu items "Selection" and "Select files / folders by extension" or apply Alt + Num +.
If you need to rename only a part of files with a certain extension, then in this case, first sort the contents of the directory by type. This will make it more convenient to search for the desired objects. To do this, click the name of the field "A type"... Then, holding down the key Ctrl, left-click ( Paintwork) by the names of the elements for which you want to change the extension.
If the objects are arranged in order, then click Paintwork on the first of them, and then, holding Shift, according to the latter. This will select the entire group of elements between these two objects.
Whichever selection option you choose, the selected objects will be marked in red.
- After that, you need to call the tool for group renaming. This can also be done in several ways. You can click on the icon "Batch renaming" on the toolbar or apply Ctrl + M(for English versions Ctrl + T).
Also the user can click "File", and then select from the list "Batch renaming".
- The tool window starts "Batch renaming".
- In field "Extension" just enter the name you want to see for the selected objects. In field "New name" in the lower part of the window, the options for the names of the elements in the renamed form will immediately be displayed. To apply the change to the specified files, click "Run".
- After that, you can close the window for group name change. Through the Total Commander interface in the field "A type" you can see that those elements that were previously selected have the extension changed to the one specified by the user.
- If you find out that you made a mistake during the renaming or for some other reason wanted to cancel it, then this is also quite easy to do. First of all, select the files with the changed name in any of the ways mentioned above. After that, move to the window "Batch renaming"... In it, click "Rollback".
- A window will open asking if the user really wants to cancel. Click "Yes".
- As you can see, the rollback was successful.
Method 2: Bulk Rename Utility
In addition, there are special programs designed for the mass renaming of objects, which are also effective in Windows 7. One of the most famous of these software products is the Bulk Rename Utility.
The main disadvantage of this method is that the Bulk Rename Utility application is not Russified, which creates certain inconveniences for the Russian-speaking user.
Method 3: using "File Explorer"
The most popular way to change filename extension is to use Windows Explorer. But the difficulty is that in Windows 7, by default, the extensions in the "Explorer" are hidden. Therefore, first of all, you need to activate their display by going to the "Folder Options".
- Go to "Explorer" to any folder. Click "Arrange"... Next in the list, select Folder and Search Options.
- The "Folder options" window opens. Move to section "View"... Uncheck the box "Hide extensions"... Push Apply and "OK".
- Now the names of the formats in the "Explorer" will be displayed.
- Then go in the "Explorer" to the object, the name of the format for which you want to change. Click on it PKM... Choose from the menu "Rename".
- If you do not want to open the menu, then after selecting the item, you can simply press the key F2.
- The file name becomes active and available for editing. Change the last three or four letters after the dot in the name of the object to the name of the format that you want to apply. The rest of his name does not need to be changed unnecessarily. After performing this manipulation, press Enter.
- A miniature window opens, informing that after changing the extension, the object may become inaccessible. If the user consciously performs actions, then he must confirm them by clicking "Yes" after the question "Do you want to change?".
- Thus, the format name was changed.
- Now, if there is such a need, the user can again move to the "Folder Options" and remove the display of extensions in "Explorer" in the section "View" by checking the box next to "Hide extensions"... Now you should click Apply and "OK".
Method 4: "Command line"
You can also change the filename extension using the Command Line interface.
But, of course, using the "Command Line" to change the filename extension of only one file is not rational. It is much easier to carry out this procedure through the "Explorer". It's another matter if you need to change the format name for a whole group of elements. In this case, renaming through "Explorer" will take a lot of time, since this tool does not provide for performing an operation simultaneously with an entire group, but the "Command Line" is suitable for solving this problem.
Using the "Command Line", you can solve more complex problems when changing the extension of items located in the same folder. For example, if you need to rename not all files with a certain extension, but only those of them that have a certain number of characters in their name, you can use the "?" Sign instead of each character. That is, if the "*" sign denotes any number of characters, then the "?" implies only one of them.
As you can see, there are several options for changing extensions in Windows 7. Of course, if you need to rename one or two objects, the easiest way to do this is through the "Explorer" interface. But, if you need to change the format names for many files at once, then in order to save time and effort, you will have to either install third-party software or use the capabilities provided by the Windows Command Line interface.
Imagine:
- file is in front of you. By double-clicking, Windows prompts you to select the program with which to open it. And who knows what kind of file it is, what extension it has and what program can open it
- Dangerous situation. The file greetings.jpg came to you by mail. You decide it's a picture and you open it. And the true extension, as it turns out, was hidden from you - the file was called greetings.jpg.exe and was virus!
- The file came by mail again. Exactly the executable file with the extension exe that you are waiting for. But the mailer for security purposes (as in the previous paragraph) renamed the file, adding the safe extension to it. You are trying to rename a file, but you are not offered the option to change the extension. How to run the file is unclear.
- you have two files on your desktop and look exactly the same. Both the names are the same, and the pictures are the same. And one of them is doc and the other is rtf. It's time to get confused.
In these cases, you just need enable display
Or a situation like this:
- you downloaded the archive from the Internet, but the browser for some reason saved it with htm resolution (web page resolution). Naturally, you will not be able to unpack such an archive.
You need change file extension to the correct one.
What to do in this case?
- Specify the display of extensions in the Windows settings.
- Use a file manager.
You can change the formats (extensions) of some files by simply renaming them.

I recommend not hiding file extensions on your computer if you are not familiar with them yet. Open file extensions will help you quickly learn which extension belongs to which type of file, and if you come across a file-virus, for example, a picture comes by mail, and its extension is EXE or BAT (executable files), then you will never open such file.
Also, file extensions are often shown by default in many file managers, for example, Total Commander.

And lastly:
Remember! As a rule, changing file extensions often makes it impossible to open and edit them in the future. Therefore, you need to be very careful when experimenting with extensions. However, some file extensions change without much effect, for example a text file with a txt extension can easily be turned into an html web page that opens in a browser.
It is best not to resort to changing file extensions, but to save files in the desired format, use the "Save As" command, which is usually located in the "File" menu of all common programs. For example, you can save a Word 2007 docx document in the Word 2003 doc document format. A simple change of the document file extension using the "Rename" command will make the docx file unreadable.

The extension is necessary so that the operating system can quickly determine what type of format a particular file belongs to. Let's say you have uploaded a photo.jpg to your desktop.

As for Windows XP, the folder settings section in this operating system is not in the control panel, but in the "Tools" section (open any folder and you will see it in the top menu). Otherwise, there are no differences.
We use the file manager
