Not supporting expressions like (mp3|wav|avi) ?
File to exclude *.*\.(mp3|wav|avi)
when reload toucan, i see that:
File to exclude *.*\.(mp3
File to exclude wav
File to exclude avi)
seems toucan use | character in the Rules.ini to merge equal rule sections, and regexp alternation operation conflicts it.
maybe decision will be to double | character in the INI? as for \ character
think this should be fixed in the next release, thanks for the report
EDIT: The easiest way to do it is to set up three file excludes simply containing mp3, avi & avi though as this should work fine.
