I have an mp3 file whose title tag contains a slash character "/". When I use the convert function in mp3tag to rename the file based on its tags, it omits the "/". For example, if the title tag is "16/05" and the artist tag is "Don Bigg", after the conversion (%artist% - %title%), the filename comes out as "Don Bigg - 1605". Does anyone know why does that happen or how to avoid it?
Thank you beforehand.

This is because the '/' is an illegal character in a filename.

Use any character in the current code page for a name, including Unicode characters and characters in the extended character set (128–255), except for the following:
```
The following reserved characters:
< (less than)
> (greater than)
: (colon)
" (double quote)
/ (forward slash)
\ (backslash)
| (vertical bar or pipe)
? (question mark)
* (asterisk)
```

Oh OK!
In fact, I have Mp3tag installed on Mac OS X ('/' character is allowed in filenames) using Winebottler, so I guess I'd have to add the '/' manually.
Thanks!

This is not recommended because of portability of such files.

I concur with LosMintos, why don't you use a '-' (dash) instead ?
From 16/05 to 16-05 it doesn't looks that bad 😉

You know the $validate function?
$validate(%artist% - %title%,-)
will make you expample to "Don Bigg - 16-05.mp3"
