|OK, thanks to all answers. This machine is DOS 7.10 stand alone. No start up folder. And, in true, I use that PC only weekends. So, once a month want to delete this log file. I need to talk a little about the prg TSTHost. Once an hour aproximatelly, this PC calls via packet radio (Like a Internet, but only for ham´s and only text files, and very primitive at 1200 baud in VHF band). Also, the BBS sometimes call to me, and other colleagues too. This prg creates a .log file in where are registered all communications, date, time, the station being connected, etc. that in few time gets very big size. And, also it creates a list (Unproto lists) of the msg´s held at the BBS (but NOT the msg itself). About 20,000 char lines, and the prg doesn´t delete automatically it, it appends at the end of the file the newer lists. In a couple of weeks, it is about 100KB or more. Too much long. So I want to delete both automatically once monthly.|
If there is a possibility of several things going wrong, the one that will cause the most damage will be the one to go wrong.
