Tom,

No worries! I have found the solution... If you use the "Save to Disc" option in Calibre you can choose your own template. If you use the {tags} parameter followed by a "\" then Calibre will export the books in seperate folders. So now I have a folder "Comics" and that can easily picked up by Ubooquity! The ePubs and the Comic files are now being handeled seperatly.

Unfortunatly Ubooquity has become less stable now. Maybe because of my 33 "tags" and thus 33 folders...
This is what I get:

Any idea? Have reboored my DS415+ NAS a couple of times - no luck.
