DWC is an archive utility and file format that was patterned after ARC, but is not compatible with that file format. It was designed to be faster and more compact than ARC, but have similar functionality.
DWC was created by Dean W. Cooper in 1986 as a higher performance alternative to the ARC (both ARC & PKARC) and ZOO file archiving tools. The file COMPARE.DOC in the reference linked below shows comparisons for both compression and time improvements over DWCs erstwhile competitors.
In 1988 the source code for the compressor/decompressor was sold to a company called DS Technologies.
- File extension: .DWC
