From Just Solve the File Format Problem
Disk Imploder is a format used on the Amiga to compress entire disks. The .dmp extension is used for such compressed disk files, and .dex for the self-extracting version that includes the program code to decompress them.
This is related to File Imploder (which compresses single files).
