Hallo is it possible to set a number and a "-" before a filename automatically? I am bussy all the time to set these manually, with the F2 function. For example:  
Child In Time must become 01-Child In Time  
Smoke On The Water must become 02-Smoke On The Water

Has everyone experience with this? Is It possible with MP3tag?

see e.g. here:

> You could do one of the following. Load the files into MP3tag. Click on the top left column header. This arranges the files in a random order. Now you could rename the files with: Convert\>Tag-Filename %\_counter% \_ %\_filename% Or you rename them straight away with the Convert\>Tag-Filename function: $rand() \_ %\_filename% or even $num($rand(),5) \_ %\_filename%

Thanks, many thanks for your solution. It saves me a lot of time. Stuppid that I didn't ask it soner. I'am 2 years busy, everyday, editing MP-3 files. Now it goes much faster.
