first question:
I have a lot of files in the format:
nnnn - Artist - Title - Year.mp3
(nnnn is the title number in 4-digit format, i.e. with leading zeros, e.g. 0032)
I have tried to use the standard action "Convert" - "Filename to Tag" but nothing seems to happen. I expected to be presented for a format dialog but I didn't. The function just exited.
I have tried to download a new version of the program and reinstall - no go.
I have checked that the files are not Read-only.
What am I doing wrong?
Second question - how should I make my own action if I wanted to make the above conversion? (i.e via the menu "Convert" - "Actions")

There was a check mark missing in the Options -\> Convert -\> Tag menu ("Show Selection Dialog")
After setting that check mark I can enter my mask.
I'd still like to know the answer to Q2, though.
Thanks!

Hi Claus,
you can use the action type Guess values with %\_filename% as source format.
Cheers,
