Why does file suffix work after it has been changed?

The format of the file is not only reflected in the suffix, in fact, the file header will contain the format information, which means that even if you change the suffix, you can still see what the format of the file is from the file itself.

Because the file suffix is not displayed, the suffix I added after the file name still belongs to the file name part.

1. Press and hold the "Win" key + "R" key on the keyboard at the same time to open the running window, enter "explorer" in the window, and then click the "OK" button

2. At this time, the file guessing manager server interface of the computer will be opened, and click the "View" button on the menu bar at the top of the file manager

3. At this time, the view settings interface of the file manager will be opened, and the "file extension" item will be selected in the view settings interface, and then the suffix will be modified to take effect:

Modify the file suffix.

It will not cause damage to the file, but if you remove the suffix, a window with a chance of corruption will pop up.

Therefore, normal files should not be easily modified or deleted from the suffix. Just choose the right way to open it

No, you can use it often.

This issue occurs because a suffix is set to hide known file names.

The solution and detailed operation steps are as follows:

1. First of all, it was found that the suffix of the txt file was not displayed, as shown in the figure below.

2. Secondly, open "This PC", as shown in the figure below.

6. Right-click the file and select "Rename", as shown in the following figure.

7. For example, change "txt" to "jpg", as shown in the figure below. In this way, the above problem is solved.

Method to remove the same prefix before the file name in batches:

Step 2, the following is the setting link, select "Replace" from the drop-down box of the naming method; Then enter the prefix character to the right of the search content to be deleted; At this point, you can preview the new file name on the right without the same prefix.

Step 3: When you think there is no problem with the settings, click the [Start Rename] button to start the software batch processor. However, a message "Rename Successful" pops up, indicating that the process is complete.
