KGB Archiver 2 for Windows

Used KGB Archiver 2 for Windows?

Editors’ Review

Download.com staffApril 14, 2020

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
HeylonNHPApril 17, 2013
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
VirtLandsOctober 11, 2012
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.
just waste of time

Great tool for archiving
JahPickneyNovember 28, 2011
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
UnderASkyOfGreyFebruary 5, 2011
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
pinkbasuSeptember 15, 2008
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.
