remove part of folderpath from filename

hi
i want remove part of folderpath from filename
part of folderpath is:
$regexp(%_folderpath%,\w:\\(.)\\(.)\\$,$2)

please help me

Sorry, I dont believe you.
Either you address %_filename% then all \ are illegal and you really get only teh plain filename.
Rr you address %_folderpath% but then the filename is not included.

no dear friend i split folderpath
i want characters after last
for example
folderpath is: N:\MUSIC VIDEO\Lady Gaga
filename is: lady gaga-bad-romance.mp3

i want change filename to: -bad-romance.mp3

What have you stored in the tag fields?
But even the filename you show now has no \ in it.

It would be easiest to write a new filename with
Convert>Tag-Filename: %title%
