KGB Archiver

CNET Editors' review

KGB Archiver's developers tout their tool for its high compression rate, but its performance in our tests left us dissatisfied.

This app opens with a compact, slightly cluttered interface with the basic components: a field for listing files to compress or expand, a field for specifying the location of the output file, the level of compression, options for passwords, and so forth. We initially liked that it offered nine levels of compression, from Minimal to Maximum, but our tests with the midrange Normal and Good settings weren't satisfying.

For instance, we compressed a 23.5Mb file using the Normal setting: KGB Archiver worked 3 minutes and 15 seconds to output a file the same size as the original file. Using the Very Good setting, KGB worked 21.5 minutes to turn the 23.5Mb file into another 23.5Mb file. Not what we were hoping for at all.

When we want a compressed file, we want the output to end up smaller than the original file. That's not at all what we got with this free app with many of its compression options. Using compression rates above Good led to desired results, but that leaves several options next to useless. There are better tools on the market, including other freeware options, and we suggest you try other programs before making your decision.

    "One of the 3 best compressors out there"

    April 17, 2013  |   By HeylonNHP

    Version: KGB Archiver 1.2.1.24

    Pros

    Extremely high compression ratios.
    Easy to use.

    Cons

    Very resource intensive, meaning it's quite slow even on my 3.1 Ghz processor.

    Summary

    This compression software seems to be able to produce the worlds best compression on certain file types. It works extremely well for Microsoft office documents. It also works extremely well for quite a few other file types.

    The only compressor that comes close is UHARC, or WinUHA (Which uses UHARC). UHARC is quite a fair bit faster, and will beat KGB on a few files. 7-Zip is a faster alternative to UHARC and will again, beat it on some file types, however it is quite rare for files under 100 MB.

    KGB is slow and very resource intensive, however I do recommend you download it along side with WinUHA(UHARC) and 7-Zip for ultimate file compression on every file on the computer.

    "KGB Archiver is a unique program"

    October 11, 2012  |   By VirtLands

    Version: KGB Archiver 1.2.1.24

    Pros

    This KGB Archiver can compress some files even smaller than
    any other archiver out there. The reason that it takes longer than
    the usual compression program is because it's compressing files even smaller than usual.
    So, in fact, if another software program also compressed a file from 3.8 GB to 0.65 GB, then it would also take a long time too; It's just the nature of the math. You can't change physics. Some things just take longer when you compress things to extremes.

    Cons

    The cons are that it unexpectedly shuts down (crashes)when running
    sometimes. I don't know why. Maybe my machine is complex.

    Summary

    Nice invention.

    "Great tool for archiving"

    November 28, 2011  |   By JahPickney

    Version: KGB Archiver 1.2.1.24

    Pros

    Offers greater compression than many other archiving programs. It's easy to use, even for those of us who are new to these things.

    Cons

    Depending on the degree of compression you choose it can take a very long time to finish even medium size files.

    Summary

    I would recommend KGB to anyone who has a lot of files they need store. If the file type can be compressed this tool will get the job done well. Just make sure you have time to let it work.

    "NICE COMPRESSION but it's VERY SLOW"

    February 5, 2011  |   By UnderASkyOfGrey

    Version: KGB Archiver 1.2.1.24

    Pros

    This application offers an very good file compressor. It compressed 3.8GB down to about 650MB.

    Cons

    The app is EXTREMELY slow. It's so slow, it's almost unusable. It took about 6 hours to decompress the 650MB file (this is the file that was originally 3.8GB).

    Summary

    Overall, it's a handy little tool. However, compression and decompression will take quite an extensive amount of time. I give it a 3/5.

    "I GOT HOLD OF THIS NICE & COMPACT SOFTWARE FROM THE NET"

    September 15, 2008  |   By pinkbasu

    Version: KGB Archiver 1.2.1.24

    Pros

    IT HAS A MARVELOUS COMPRESSION CAPACITY WHICH CAN SIGNIFICANTLY BRING DOWN THE SIZE OF FILE FROM MEGABYTES TO BYTES. BEST OF IT IS THAT IT IS FREE.

    Cons

    THIS PRODUCT IS SLOW TO DECOMPRESS OR COMPRESS FILES.

    Summary

    NICE OVER ALL COMPRESSOR & DECOMPRESSOR.
