Ami-FileSafe (AFS, Ami File Safe, Ami-File-Safe, AmiFileSafe; people can't get it straight how to punctuate it) is a filesystem for Amiga computers, released in the mid-1990s by Fourth Level Developments. A later version was Ami-FileSafe Pro, with a limited version available as Ami-FileSafe User. PFS was also a compatible successor to it. It was commmercial, proprietary software. It's not to be confused with AmiSafe, a password-storing program for the Amiga.
