||||||
|
## Archiving and compression
|
||||||
|
# Open source file format. Used by 7-Zip.
|
||||||
|
*.7z
|
||||||
|
# Mac OS X, restoration on different platforms is possible although not immediate Yes Based on 7z. Preserves Spotlight metadata, resource forks, owner/group information, dates and other data which would be otherwise lost with compression.
|
||||||
|
*.s7z

||||||
|
# Old archive versions only Proprietary format
|
||||||
|
*.ace
|
||||||
|
# A format that compresses and doubly encrypt the data (AES256 and CAS256) avoiding brute force attacks, also hide files in an AFA file. It has two ways to safeguard data integrity and subsequent repair of the file if has an error (repair with AstroA2P (online) or Astrotite (offline)).
|
||||||
|
*.afa

# Originally DOS, now DOS and Windows Created by Yaakov Gringeler; released last in 2003 (Compressia 1.0.0.1 beta), now apparently defunct. Free trial of 30 days lets user create and extract archives; after that it is possible to extract, but not to create.

Currently, Safari is the only browser that supports this form of extraction; however, the images can be manually extracted as well. This format can also be password-protected or encrypted with 128-bit or 256-bit AES encryption.

# Self Dissolving ARChive Commodore 64, Commodore 128 Commodore 64, Commodore 128 Yes SDAs refer to Self Dissolving ARC files, and are based on the Commodore 64 and Commodore 128 versions of ARC, originally written by Chris Smeets. While the files share the same extension, they are not compatible between platforms. That is, an SDA created on a Commodore 64 but run on a Commodore 128 in Commodore 128 mode will crash the machine, and vice versa. The intended successor to SDA is SFX.

# An archive format designed for the Apple II series of computers. The canonical implementation is ShrinkIt, which can operate on disk images as well as files.
