Maximum total size of files (before compression) is 2GB. The number of files that can be compressed in a single job is limited only by the amount of memory available. UHARC is becoming a power-user's favorite, able to build large archives with high compression ratios. UHARC High performance file archiver / compressor. Go to M Software's Downloads page for older versions of RK in Italian, the latest Win GUI version, and other related tools. The Windows version has the usual drive/dir select box.Īuthor: Malcom Taylor / M Software, New Zealand (2000). It's buggy too: An opening screen presents options to click OK to install, or Cancel, but they do not really exist, and pressing any key installs. The DOS version is rigid, installing in C:/RK with no options. However I've yet to get it working on a 386SX/20 w/8MB RAM, no success either compressing or decompressing with default options.īoth download files are packed SFXes.
SFX archives also require an 80386+ target system. The DOS version is a 32-bit DJGPP build, and require 80386+, 4MB RAM, and a DOS Protected Mode Interface ( CWSDPMI or other).
Script language: "Scripts can be added to archives to enable some automatic functionality, such as archive comments and self extractor defaults.".Both the DOS & Win versions can create self-extracting archives (SFXes) for DOS, Win32 GUI and Win32 console.High compression is gained at the cost of speed. Outstanding compression statistics for a variety of file types and collections (see Archive Comparison Test).Although it lacks some basic maintenance features (e.g., no "delete file from archive" option), and is not optimized for speed, it possesses several attractive features: RK is a high performance archiver, in versions for DOS and Win32 console. Note: While the DOS32 programs work under Win32, the -xN.* versions are better.
The 32-bit DOS versions require an 80386+, FPU or emulator, and a DOS Protected Mode Interface ( CWSDPMI, or OS services).
ZIP and UNZIP packages for DOS contain both 16- and 32-bit versions of their programs, and docs. WiZ combines ZIP and UNZIP with a Windows GUI. Encryption and decryption are now built in to the ZIP and UNZIP EXEs. UNZIP packages contain other utilities that give detailed zipfile info, extract in a pipe, and create self-extracting archives. ZIP packages contain other utilities that add or delete comments to zipfiles and split zipfiles. Although creation of self-extracting EXEs is possible, it's not elegant it adds 30K to file size, and creates a file potentially not readable by PKZIP compatible viewers. ZIP has one compression method (deflation) and can store files without compression.
Source code is also available.Īlthough ZIP still can't span a zip file across multiple floppies, it does most everything else as well as PKZIP (compression size, speed). Unlike PKZIP, it is a completely free program. Info-ZIP was developed primarily to provide cross-platform PKZIP compatibility across a variety of operating systems (DOS/Win, Unix, OS/2, Mac, VMS, Linux, Amiga, Acorn, SGI, Atari, etc.). The command line syntax varies from PKZIP/UNZIP, and additional options have been introduced. It is format compatible with PKZIP but the resemblance ends there. "Compatible" does not equate to a cheap knockoff or clone in the case of Info-ZIP. Info-ZIP (zip & unzip) PKZIP compatible file archiver.
