What is the Best Compression Program?

[gamenamababy]

what the best Compression program that u know and use 7-zip,uharc or kgb archiever

i try them there are good as i know

7-Zip is an open source file archiver with the high compression ratio predominantly for the Microsoft Windows operating system. It operates either as a command line program or with a graphical user interface. It also features integration with the Windows shell environment. 7-Zip is free software, developed by Igor Pavlov and distributed under the GNU LGPL license.

The main features of 7-Zip:
- High compression ratio in new 7z format with LZMA compression
- 7-Zip is free software distributed under the GNU LGPL
- Supported formats:
Packing / unpacking: 7z, ZIP, GZIP, BZIP2 and TAR
Unpacking only: RAR, CAB, ISO, ARJ, LZH, CHM, Z, CPIO, RPM, DEB and NSIS
- For ZIP and GZIP formats 7-Zip provides compression ratio that is 2-10 % better than ratio provided by PKZip and WinZip
- Self-extracting capability for 7z format
- Integration with Windows Shell
- Powerful File Manager
- Powerful command line version
- Plugin for FAR Manager
- Localizations for 65 languages

Changes in 7-Zip 4.44 Beta (January 20, 2007) for Windows:
- Speed optimizations for LZMA, Deflate, BZip2 and unRAR.
- 7-Zip now supports file pathnames longer than 260 characters.
- Some bugs were fixed.
- New localizations: Bangla, Bashkir, Nepali.

And

Uharc ultimate zipper

This zipping software is very powerfull one it can convert 10:1 ratio that is if you give 10 mb file it will covert it to 1 mb file

Ánd

KGB Archiver - Compress 1GB into 10MB



Well, this software promises to Compress 1GB into 10MB same as Uharc ultimate zipper

I could not test it due to its Sytem Requirement

KGB Archiver

KGB Archiver is the compression tool with unbelievable high compression rate. It surpasses even such efficient compression tool like 7zip and UHARC in terms of the abilities.

KGB Archiver is an application created to allow you to compress and decompress files.

What Ur using

I'm using WinRAR. I was using 7-zp because it was faster. However, it's not as user friendly as WinRAR, so at the end of the day, WinRAR can do things overall faster.

But 7-zip is 64bit and WinRAR is 32-bit. That's the only plus point 7-zip has and it's significantly faster than WinRAR if your are compressing/decompressing lots of small files (i.e. the compression/decompression job is CPU bound, rather than I/O bound)

WinRAR is easy to use. Some time back there was AIN compressor, which was a command line one, very very fast and had very good compression ratios. But now looks obsolete as it is only command line. WinZip is good because it has extensions for WinXP file systems. you can browse, view, cut, copy and edit files a WinZip archive as it is in a WinXP folder.

WinAce has probably the best compression ratio, but it is too expensive.

I'm not worried about compression ratio. I need speed, even at a cost of low compression ratio
With huge hard disks and large flash drives, I don't think the compression ratio matters much.

Then why not use "store " for compression ratio? Then every compressor is very fast. Even with store method, there is some compression as a sector of the HD is fully used, unlike in multiple files.

Yes, there will be compression.
But time is not completely dependent on the compression ratio. It's a compromise between compression ratio and size of the archive, because the slowdowns can be caused by either the CPU (high compression ratio) or hard disk (larger archive). For fastest archiving strategy, the CPU utilization should be very close to 100%, but not 100%.
