Hi all
New to Mp3tag. Have searched the forums for an answer to my question and found many questions that is similar to mine, but nothing that answers my precise problem.
I have a lot of files, that contain different numbers at the beginning of each filename. I would like to remove these numbers. My files look like this:
2285186-1-7\_Swans\_Volcano.wav
9008863-1-1\_Alcest\_Opale.wav
2360934-1-10\_TV On The Radio\_DLZ.wav
Is it possible to create an action, which removes the numbers, so the filenames will look like this:
\_Swans\_Volcano.wav
\_Alcest\_Opale.wav
\_TV On The Radio\_DLZ.wav
Hope to hear from you,
All best
Anders

Thank you so much!
I used this:
$regexp(%\_FILENAME%,'^[\d.-]+(.\*)',$1)
My files now look like this:
\_Swans\_Volcano.wav
\_Alcest\_Opale.wav
\_TV On The Radio\_DLZ.wav
If I want to remove the first "\_", is there a way to make changes in: $regexp(%\_FILENAME%,'^[\d.-]+(.\*)',$1)
?
Thank you kindly for your help 🙂

Use for the initial filename (with number):
`$regexp(%_FILENAME%,'^[\d\.\-]+_(.*)',$1)`
To get rid of the leading underscore (for those files that have been processed already):
`$regexp(%_FILENAME%,'^_',)`
