Maybe someone who's better at basic scripting than me can help me out.
Say I have a directory with files that have extension .srt.
I have a batch file that performs some functions, and I would like to add the ability to batch rename .srt files to .en.srt.
I have tried this, but the problem is if a file is already named correctly, it will become filename.en.en.srt:
whats a better way to do this? thanks!
