As fatspirit and 420 wrote For example: I have two .torrents - №1 torrent i've downloaded, №2 i want to reseed. They both have images inside them. Images are md5-identical, but with different filenames. .torrent №2 besides of image have additional file(an .nfo), i don't have this file. I relocate image from .torrent №2 to point on image from .torrent №1. And after rechecking of .torrent №2 image have 99.8%. But in pieces view there are all pieces present. This is the problem. If I start .torrent №2, then it downloads one piece, but md5 of image isn't changed - these piece carries an .nfo file inside and a part of image that I already have. I understand, that some pieces carry data from two files and do not ask to fix this. I want to disable hash check of relocated files (i will control integrity of files myself).
