jalaffa Posted December 16, 2007 Share Posted December 16, 2007 UPX (Ultimate Packer for eXecutables) is a free, portable, extendable, high-performance executable packer for several different executable formats. It achieves an excellent compression ratio and offers very fast decompression. Your executables suffer no memory overhead or other drawbacks because of in-place decompression.UPX is copyrighted software distributed under the terms of the GNU General Public License, with special exceptions granting the free usage for commercial programs as stated in the UPX License Agreement.UPX uses the NRV compression library for compression services. A compatible but somewhat less efficient OpenSource implementation is available through the UCL compression library.UPX is a versatile executable packer with the following features:• excellent compression ratio: typically compresses better than WinZip/zip/gzip, use UPX to decrease the size of your distribution!• very fast decompression: ~10 MB/sec on an ancient Pentium 133, ~200 MB/sec on an Athlon XP 2000+.• no memory overhead for your compressed executables because of in-place decompression.• safe: you can list, test and unpack your executables. Also, a checksum of both the compressed and uncompressed file is maintained internally.• universal: UPX can pack a number of executable formats.• portable: UPX is written in portable endian-neutral C++• extendable: because of the class layout it's very easy to add new executable formats or new compression algorithms• free: UPX is distributed with full source code under the GNU General Public License, and may be used freely even with commercial programs.Changes in version 3.02 (16 Dec 2007):* fix unmapping on arm-linux.elf* fix error checking in mmap for i386-linux.elf [triggered by -fPIE]* bug fixesHomepage - http://upx.sourceforge.netSize: 318 KBDownload for WindowsDownload for DOS Link to comment Share on other sites More sharing options...

Halcyon Posted December 17, 2007 Share Posted December 17, 2007 This is a compression tool for EXECUTABLES. It's not in the same category as 7zip, RAR, KGB Archiver, etc.It's main use is for EXE's. Link to comment Share on other sites More sharing options...
Anteus Posted December 17, 2007 Share Posted December 17, 2007 OT does KGB Archiver have a higher compresion ratio than UHARC? Link to comment Share on other sites More sharing options...
HATE9X Posted December 17, 2007 Share Posted December 17, 2007 OT does KGB Archiver have a higher compresion ratio than UHARC?It does but when I used it earlier with max compression it could take more than 5 mins to compress & decompress a few megs file.. :P Link to comment Share on other sites More sharing options...
