I've used the regular expression given in the forums to take filenames that are all one word (ie: ThisIsTheFilenameAllOneWord) and change it to having spaces before each of the capital letters so it reads: This Is The Filename All one Word.
It now doesn't work with 2.26f.
For reference, the expression involves the following two entries:
1) "/u" is replaced by " $0"
2) "^/s" is replaced by ""
Please let me know what I need to do to get this working again (or what needs to be done behind the scenes to do so.) I use it on probably a daily basis in restructuring filenames and tags.
As always, thanks for credating MP3 tag ... which is such a great, slick and useful tool for handling what would otherwise be a mundane, time consuming and boring task.
