I've tried to write a TSR which could : record all these actions, but I can't seem to find the interrupt which : handles file i/o. Can someone tell me what it is? Unless I'm horribly mistaken, doesn't the DOS interrupt (21h) handle file i/o? I would recommend getting a copy of Ralph Browns Interrupt List (I think thats the name), which is a big listing of all interrupts and their functions. Specifically, look at INT 21h,3D and 3E, open/close file with handle. -- jon klippenstein internet: klip AT cryogen DOT com uucp: alberta!ve6kik!dparrot!{root,klip} ham radio: ve6klp
