I would, but I have 8k .epub files.
When using AllDupe:
I created a folder and in it, I added 'Becca Fitzpatrick - Hush, Hush' and 'Becca Fitzpatrick [Hush Hush Saga 1] Hush Hush' into a single folder and ran a check with the .epub filter.
I receive the same message I got from Doublekiller.
'1 Folder and 2 Files were located, but no duplicates were found.'
Could someone tell me please why this would be?
