ARC is used to create and maintain file archives. An archive is a group of files collected together into one file in such a way that the individual files may be recovered intact.

Archive file format. Most commonly associate with DOS-based machines. This format stores 1+ files in a compressed format in an archive file.

Compressed archive Common

ark file that has been compressed with the arc program or similar will get the "arc" (and very rarely the "ark") extension. Its performance is somewhat less than gzip & zip, but decompression programs exist on virtually every platform. Like zip, arc does not require a separate tarring step; it uses its own method to do the equivalent.

COMPRESSED You will need PKPAK.EXE

An old and inefficient format for archiving and compression. File Type: Binary If you need to exchange files with an older operating system or have old files to read on a new machine, you may need an ARC program. Stuffit Expander for Windows will work for the PC (sitexxx.exe). For the Mac try something called ARCMac.

A method of compressing files using PKARC. An out-of-date method, but there are still plenty of them about.

Arc file compression application developed by SEA. Compressed files have a filename extension of ARC. Use the same application to decompress archived files under DOS/Windows. Use MacArc, by Leo Laporte and Ray Terry, or Aladdin's free StuffIt Expander to decompress ARC files under MacOS.

Archive (file name extension)

ARC is a file format by SEA (System Enhancement Associates) that was very popular before Phil Katz's introduction of the ZIP format. The file format and the program were both called ARC. The ARC program essentially made obsolete the use of combinations of the SQ program to compress files and the LU program to create .LBR archives by combining the functions of both compression and archiving into a single program.
