How to easily change the file extension

In Windows, we often see small file icons. How does Windows know the types of these files? the original file type is determined by the file extension, generally, different extensions represent different types of files. Windows is very intelligent (after all, it is not a white meal). If a file with a certain extension has been registered and opened using a program, wind95 will display the program icon on the left side of the file name. It clearly shows that the file can be opened with the program indicated by the icon and the extension is hidden. But there are some advantages and disadvantages in everything. It is very difficult to change the extension in Windows (some readers may think about it, but it is not easy. In Windows Resource Manager, select the file to be renamed, right-click and select the "RENAME" command in the shortcut menu, or simply click the "RENAME" button on the toolbar? In fact, this method can only change the file Master name, but cannot change the file extension, because the file extension is not displayed yet !). In fact, we can solve this problem by looking at a solution.
1. Change it in the Resource Manager
If we directly right-click the file name, select "RENAME", or press the F2 key to change the file name, it will certainly not work. However, we may try to open "my computer" or in the resource manager, click "Tools" \ "Folder Options", and then select the "View" tab, deselect the option "Hide extensions of known file types" and press F5 to refresh your resource manager window, the extension names of all types of files are displayed (2). In this case, select the file to be renamed, right-click the file, and select the "RENAME" command in the shortcut menu, you can also click the "RENAME" button on the toolbar to change the file extension as before.


However, we recommend that you restore the original settings after the changes are completed. In Windows, users are generally not allowed to see the file extension. It is a fear that once a user changes the file extension, it is different from the extension already registered in the registry, and the file opening method does not work anymore, it cannot be opened by the original program. Therefore, we recommend that you select the check mark before "Hide extensions of known file types" to be compatible with windows ". This method can be used to change any file, so long file names won't go wrong, but it is troublesome to do so.
2. Use the File Manager to modify
Windows 3. users of X will not be unfamiliar with the file manager, but those who directly use Windows 9x and Windows 2000 will not necessarily know it, but the practice has proved that, sometimes it is easier to use a file manager than to use a Resource Manager (except that its operation interface is still 16 bits). For example, when you change the file name, it is better than the resource manager, as long as we select a file in the window and click "" \ "file" \ "RENAME", the extension can be easily changed in the open rename window (3 ). At the same time, the File Manager also provides some functions, such as renaming and copying files in batches and selecting files with a certain extension. It can be seen that the file manager is a professional file manager after all, in some aspects, you are competent.

3. Modify the doscommand
Although the current machine uses a standard Windows GUI, DOS can still exert its residual heat at some critical moments. If you want to change new1.bmp to new1.ico, enter the code such
Ren new1.bmp new1.ico
(4)

Press enter to complete the task.
Although it is inconvenient to change the name of a long file name in DOS, it can use wildcards to change multiple files!
4. Change with ACDSee
Whether or not to display the file extension in ACDSee depends on the settings in windows. If we select the file whose name is to be changed, press the Alt + R shortcut key to display a new name window, in this window, there is a change to the previous file name (5), including the file extension), then re-enter the file name with the extension. However, this method has a major drawback, that is, it must rename two or more files, and it is powerless to one file. Therefore, it should be very OK to change the file name and extension in batches. If you cannot display all files in ACDSee, select "other files" under "filter" (6 ).

5. Use professional renaming tools
Now there are a lot of professional online renaming tools, you can go to the home page to find a (http://bj.onlinedown.net/ty_rename.htm), such as the author downloaded a free software named batch rename, I feel really good to use.
However, I would like to remind you that most programs now support automatic extension, so you only need to give the file the primary name when saving the file. ...... It's ugly.
