DMS file extension - Amiga compressed archive

What is dms file? How to open dms files?

This is a floppy disk image compressed with DiskMasher, an Amiga disk compressor.

DMS (the Disk Masher System) is a proprietary Amiga disk archiving format that was widely used to store and distribute disk images before emulation became widespread.

It supports built-in compression, and a few copy protection schemes. DMS is supported well on original Amiga systems, but remains less popular than ADF in the emulation community.

Mime types:

This dms file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
