I just had this 7zip not in context menu issue, and have seemingly narrowed it down to the file's 'Availability status', i.e. whether it's 'Available on this device' or only 'Available when online'. I've notice that if it's 'Available when online' the 7zip option doesn't show.
I've been pointed to Tagger# as I need to re-tag several hundred media files that are in MP3 & WMA pairs, but I need to store the whole date and not just the year. The --Year parameter only accepts a year, but via another Windows gui app 'Tag&Rename', I can enter a full date in "YYYY/MM/DD" format, which gets written as the ID3v2 tag "TYER" for MP3 files, and tag "WM/Year" for WMA. Can Tagger# achieve this? Also, is wildcard support going to be added at all?
