    As the title says "How to extract .kgb files faster?"
    I have a .kgb file the size is 82.3 MB and the size before commpression was 11.2 GB!
    Now it shows remaining 150 hours i can't do that that longer!
    So is there is any way to extract it faster atleast in 5hrs?
    And i am really sorry if this is in the wrong catagory!
    And sorry for spelling mistakes

    Forget whatever I said. I misread the archive file size. FordGT90Concept is probably right here. At a 83.3MB archive, 150 hours is horribly long...

    My guess is what ever program you're using is doing it wrong. It's overflowing. Something 82.3 MB, no matter what it contains, shouldn't take more than a minute to process.

    Keep it on topic gents.

    The system does have to write 11.2 GB to the hard drive during extraction, but 150 hours is ridiculously long..

    Sounds corrupted if the compressed form is only 80MB.

    Won't KGB Archiver extract it's own file?
    Why are you using uniextractor (which uses KGB anyway)?

    it is .kgb not .rar or .zip
    KGB are known for slow and highly compression but not that slow
    Well uniextractor is my primary extractor and i download KGB extractor might extract it faster

    This is the answer, no compression tool would take 11GB of data down to 80MB

    It is corrupt no ifs or buts about it.

    How long did it take to compress that 67GB? I still find this dubious, might have to play with it myself later.
    Still dont believe it can compress to 1/100th the size

    KGB Archive uses the PAQ6 (or PAQ7) compression algorithm and has unbelievable compression ratios. Especially if you select max compression.

    If you used max compression (and encryption) it is going to be slow. Really slow.
    I've never used it though..

    I don't know, gopal. Extraction may be much slower than compression since it has to write the 11GB instead of just reading it.

    There is the possibility that the 150 hours is an estimate and it won't take that long once it gets going. Hard to tell though.

    I pulled a copy of KGB and told it to compress my Steam folder (124GB).
    10 minutes later it's still looking through the files and has not started compressing yet. :D

    It's using all 4 cores too.

    20 minutes, still scanning for files. Overall CPU usage at about 25%

    It is highly unlikely that video, which is typically already compressed, would go from 11GB to under 100MB. I've seen compression ratios of the sort before, but only on plain text files.

    I killed the Steam folder compress as I ran out of patience.
    Told it to compress a folder full of JPGs. The program crashed.
