Hello all,
I have a bunch of mp3s that don't have tags on them. The way the files are named are in the following format:
Artist - Title.mp3
What I'd like to do is write two regular expressions:
1. To add the Artist tag by looking for all characters before " - " in the filename.
2. To add the Title tag looking for all characters after " - " in the filename
Can this be done? If so how would you do this using the Mp3tag application? And can it be applied to multiple files at once?
Thanks,
Dan

The basic concept is the notion of a format string which describes the structure of the name to import from. The format string is built of either standard text (e.g., Music), placeholders (such as %artist%, %title%, ...), or backslash characters \ that denote directory structures. Here is an example that imports t…
It'd be `%artist% - %title%` in your case.
