File in use

[George J.]

I have developed a document management system (as part of a practice management system) which as one would expect makes extensive use of various file manipulation functions (copy, move, delete, etc.). Is there a way with 360works to test if a file is in use? I could error trap on the other functions (e.g. copy) but that is inelegant and I would prefer to start off with a first check, i.e. is the file in use before embarking on what are some quite complicated and lengthy routines.

Any assistance/suggestions would be much appreciated.

Thanks.
