The question mark (?) is also a wildcard, but it represents a character of the original name you want to keep as part of the new name. The asterisk (*) is a wildcard that tells the ren command to rename everything with a specific extension. In the command, replace "FILE-EXTENSION" with the extension to change and "FILE-NAME" with part of the name to add to the files. Type the following command to rename the files in bulk and press Enter: ren *.FILE-EXTENSION ?-FILE-NAME.*.


Once you complete these steps, Command Prompt will rename the file with the new name available in the command. Repeat step 5 to change the name of the remaining files.
