Archive Comparison Test - by Jeff Gilchrist
(DOS/Windows) - May 12, 2002 Edition


This is the archiver index page for the DOS/Windows archivers tested in ACT. It contains links to the author's web page if available or to download the archiver itself, the author's e-mail address, information about the archiver such as compression algorithms used, special features available and minimum system requirements. More archiver entries and more info such as which file formats each archiver can create/read will follow in the future.

Many of these programs can be downloaded from the SAC Pack Archive.

Note, due to all the spamming efforts recently I have removed the mailto: links for the authors and put a space before and after the @ in their e-mail address. Copy any paste their e-mail address and then remove the spaces to contact them.

Features Legend:
A = Authentication Verification (Security Envelope)
E = Encryption (Ability to encrypt/garble files in archive with password)
G = GUI (Graphical or Text Shell to manage archiver functions)
L = Windows Long Filename Support
M = Multi Disk Spanning (Ability to span an archive over two or more disks)
P = Data Protection Encoding (Stores Error Recovery Info)
S = Solid Archives (All files compressed together as one instead of individually)
X = SFX (Ability to create Self-Extracting Archives)
