Been using Mp3tag for a long time, but this is the first problem I've had with it. Lately when I convert tag-to-filename in a folder that has a leading space (to keep it at the top of the directory it is in) it deletes the space and saves the mp3's in a newly named folder. For example: if I have a folder of mp3's named "General" (where the "" stands for an empty space), after converting the mp3's I find them moved to a folder called simply "General" (with the empty space removed).
Hope that's clear enough. Any way to stop this behaviour?
