.ARK File

File extension ark is related to ARC, a lossless data compression and archival format by System Enhancement Associates (SEA). It was very popular during the early days of networked BBS.

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.

ARC compresses multiple files into one - but unlike ZIP, not entire directory trees. The arc format was the subject of quite a bit of controversy in the 1980s - an important event in the open source debate.

MIME types:

Files with ark extension can be most often found as special archive files created by the CPM/Port of ARC File Archiver.
