Hmmm.. Thanks much for the vital information you all. When I remove ebooks from the Calibre, since it can get literally swarmed, I 'Delete everything' after saving to disk.. Even .opf files, sadly, which I'm guessing are needed for dupe finding.
If I were to delete everything EXCEPT the .opf files, will it clear my Calibre window of books and yet save the library info for the next batch of loaded books so I can find the dupes, or how would that work?
By the way, I have Windows 7 64bit on both my laptop and my PC.
Also, I use Dupe Cleaner, but sometimes it won't work correctly, ie, it won't find the proper files.
I mostly use Anti-Twin, which is a two-edge sword. While good, there are significant issues.
When searching Similar files, they give you a ratio. Compare:
Ratio set for %100
The Hollows 01 - Dead Witch Walking.epub
Dead Witch Walking.epub
Results: 0 Duplicates found.
The Hollows 01 - Dead Witch Walking
The Hollows 11 - Ever After
Ratio set to %90
Duplicates found: 3
The Hollows 01
Dead Witch Walking
The Hollows 11
Yeah. See my issue? With this method, Series 1 and Series 8 are similar books, while Dead Witch Walking.epub and The Hollows 1 - Dead Witch Walking.epub are not.
