I am trying to rename my mp3 files and some of them have question marks and other characters at the end of the title. For example right now it is showing as what's really happening?. How do I remove the question mark and other characters?
Thanks

You can remove single characters with an action of the type "Replace" for TITLE
Search string: ?
Replace string:
(leave empty)
If you want to remove these characters to create valid filenames, you can simply use the function Convert\>Tag - Filename. This produces valid filenames and leaves out invalid characters.
Also, there is the scripting function $validate() which you can use in format strings.
