Executables and text files conventionally had no suffix. * DEC systems preserved the separation of fields, and the most popular of the later micro-based systems (CP/M, MS-DOS) copied this idea. * Unix copied the Multics usage of no extensions for executables. Text files could have a range of different suffixes, depending on their intended usage. The article doesn’t mention version numbers, which are/were found on some DEC-proprietary systems: TOPS-10/20, VMS.
