View Full Version : open partial .7z files?
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
is there a way to open incomplete .7z archives?
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?
In the first case, it's not possible, and a limitation of the 7-Zip archive format:
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.
In the second case, I think it isn't possible, either.
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

Offset address?
If your intention is to repair a RAR you can try the countless RAR repair tools around the Web...
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...
RAR recovering - Case 2 (http://riepersnest.tripod.com/rar/step2.htm)
RAR recovering - Case 3 (http://riepersnest.tripod.com/rar/step3.htm)
