I must first of all like to say I think mp3tag is awesome - especially for helping me re-organise my music - I foolishly stored everything in directories by artist name, and obviously this is a pain when different family members want a compilation album on their player

So I have the following 2 entries in my dropdown under "tag - filename"  
F:\MyDocuments\sweep\My Music\MP3Out\Various\%album%$num(%track%,2) - %title%  
F:\MyDocuments\sweep\My Music\MP3Out\%artist%\%album%$num(%track%,2) - %title%

Now I have realised it would make my life a bit simpler (especially if I accidentally picked the wrong one) would be to use a reg expression which looks at the "Comment" tag, which I would manually set to "V" to indicate a compilation.

I'd appreciate guidance if this can be done as a single expression, please

Also is there any way of deleting entries from the "directory" dropdown

Thank you

Cheers. I wasn't too sure if I'd need double quotes round the strings (and possibly use of concatenation characters), but I got it right first time

F:\MyDocuments\sweep\My Music\MP3Out$if($eql(%comment%,V),Various,%artist%)\%album% - %year%$num(%track%,2) - %title%
