I work in a mixed environment that's mostly OSX along with Windows. When Ubooquity finished scanning my eComic library, the number of pages is doubled due to the displaying of ._filenames for EVERY SINGLE file! Generally, deleting ._filesnames is a bad idea due to the metadata they contain, so it would make sense to have these hidden by default by Ubooquity.

I have a valid comic book that I have been able to open on various comic readers on my computer. I also have the second issue to this particular series that I can read on my computer, and that Ubiquity has picked up and displays the pages just fine. However, the first issue of this series is just not working. I have re-downloaded the comic, I have uncompressed and renamed the pages (001, 002, etc.) and recompressed it. Nonetheless, it will not open this book and I can't figure out why. Here is the stack trace:

I would be happy to send the file to anyone willing to help me troubleshoot this issue (no pun intended).

Hi, 
I have a broken image icon up in the middle of the page when loading the file and beginning to read it. It is a bug? or my computer does not have this default icon or logo?

Thanks for your smart work!

I am just playing around for the first time. Installed U on the d: drive. But then deleted it and moved it to the i: drive. Recreated everything.

But it keeps creating folders on the d: drive (cache, logs, etc.) even though the same folders exist on the i: drive. And sometimes when I start U on the i: drive it gives an error referring to the d: drive. But the next time it works.

Also, another issue is that when it started scanning the books it stopped at one book and does not appear to go past it. Does that mean the metadata for the book is corrupt? How rare an occurrence is this kind of problem?

Tom, Ubooquity saves its thumbnail cache and books / comics database within the directory from which Ubooquity is ran.

On NAS systems and other environments with small OS partitions Ubooquity quickly fills up the entire partition.

Please add the capability to set where to save the thumbnail cache and database. On my system Synology auto-partitions the OS to 2.3GB and it has been filled by Ubooquity generated files. If I could set the cache to a different partition this problem would be solved.

Hey folks - when I click on documentation at the top of the page I'm directed to:
http://vaemendis.net/ubooquity/static5/documentation

I know there's at least one other page detailing Calibre support, however is there anything more?  I'm wondering what the advanced options are for example, how to set the server up with https, etc.
