Hi,
Trying to make a special action for case conversion for my filename, my filenames have 2 digits before the filename 01,02,03 etc, I have made an action for filename in mixed case but what do I insert into the "Words begin from/after any of: box so that it skips the numbers, I keep getting something like this - 01snow Patrol - Run, I still want to keep the numbers but would like mixed case for the rest of filename...
Cheers
Jay

Are those track numbers? I'd separate them from the first letter by a space, then the case conversion becomes simple. Makes reading the filename a little nicer, too.
Barring that, the obvious answer to your question is to add the digits 0 to 9 to the characters in the 'begin from/after' box.

Thank you, went for your second option as I have so many tagged with no space between track number & start of filename...
Cheers
