UHarc

From Wikipedia, the free encyclopedia

UHarc is a solid, high-compression 386+ DOS and Windows file archiver with multimedia support. It is written by Uwe Herklotz and is available as an .EXE (no source so far), but is free only for non-commercial use. Memory requirements depend on the compression method used (e.g., -mz needs less than -mx). Comparisons between WinRAR and UHarc generally show smaller filesizes with UHarc but a relatively substantial increase in decompression time (but much faster than PAQAR4, etc). The latest beta is 0.6b (01 Oct 2005), but since 0.6a it has completely replaced the 0.4 and older archive headers and is not backwards compatible. In other words, you'll still need UHarc 0.4 if you have any valuable data compressed with that version. There is a known limitation that archives must be smaller than a total of two gigabytes unpacked size. A self-extracting executable (SFX) stub is included for Windows (new in 0.6a). New in version 0.6b: unUHarc (DOS and Windows binaries, no restrictions).
