Sure! Here's the translation of the steps into English:
Open "Computer": Find the "Computer" icon on your desktop and double-click it to open it, and you will enter the "My Computer" window.
Click on "Tools": Then click on the "Tools" option in the menu bar at the top, and in the drop-down menu, find and click on "Folder Options."
Access the "View" options: In the pop-up "Folder Options" dialog box, click on the "View" tab to enter the view options page.
Disable hiding file extensions: On the "View" options page, scroll down until you find the option "Hide extensions for known file types." Make sure the checkbox in front of it is unchecked, which will prevent file extensions from being hidden. Then click "OK" to save the changes.
Rename the file: Now you can browse through your computer to locate the target file. Select the file by clicking on it once, then press the "F2" key or right-click on the file and choose the "Rename" option. In the rename text box, you can change the file extension according to your needs. After entering the new extension, press the "Enter" key to complete the renaming process.
Please note that modifying file extensions can result in the file being unable to open properly or being incompatible with the corresponding program. Make sure you are aware of the changes you are making and backup important files before proceeding.
