RFSApps is a module providing 2 commands to control the ROM aps, and *RemApp to remove applications linked with *AddApp. It is a beta version; use with care.
This relies on the singular way in which the ROM has been compiled, so it only works with RISC OS 3.7, and maybe 3.5/6. *RemApp should work with all versions.
The KillApps utilities are superceded, but still available.
