Reverse before and after a certain character

[petdenny]

Hello. I have a list of filenames that is formatted:

Title_Artist

and I would simply like to reverse it to

Artist_Title

They are always separated with the underscore, but sometimes its more than one word separated with dashes.

any idea?

Hi, try:

RegEx (1)
Enable option "Simple" in RegEx (1)
Match: %1_%2
Replace: %2_%1
