is there a way to open incomplete .7z archives?
7z manager just barks at that kind of files
oftentimes i only want to see the checksums inside the archives and clearly downloading the whole multi-gigabytes files is out of the question

With "incomplete", do you mean having just 1 part of a split archive, or having downloaded just the first few KB/MB of a single one?Quote:

In the second case, I think it isn't possible, either.Quote:
7z cannot extract "broken files" - that is (for example) if one has the first segment of a series of 7z files, 7z cannot give you the start of the files within the archive - it must wait until ALL segments are downloaded. WinZip has the same limitation.
yeah, i mean the latter.
for rar and zip it can. i usually only have to download about 10KB to able to see the whole crc values. too bad..
and other thing, could you find the offset address for a broken rar achives without a recovery record? it's very helpfull if you don't want to download the whole things

naah, all that repair tools are useless if the archives doesn't have recovery record on them.
what i mean is, for example if i have one good rar file, then one single byte at offset address xxxx in the file got screwed, is it possible to locate that offset address.
i am manage to find the address around that corrupted bytes when the file is zip archives. i just grab, redownload, enough bytes around that area and inserted it to the broken zip archives to replace the corresponding bytes and it will work like a charm.
I have found something that sounds exactly like what you mentioned...Quote:
