One of the most popular uses for this filter is to allow WordStar overlays to reside on any drive/user (either the same as WS.COM or another entirely) and to allow WordStar to be executed from any drive/user. The documentation is quite complete; the files were built from a combination of a C user interface and to M80 programs, which I will upload if demand merits. Note that the original program was a Z80-only affair; I converted it to 8080 code. UNSETDRU can de-install a redirection filter but is not necessary as long as the original file is properly backed-up before using SETDRU. -Charlie
