Task Manager has a "handles" column. I suspect it includes all kernel-object handles, not just files. So it would include thread handles, mutex handles, pipe handles, etc. It's probably a decent gauge for your purposes, though. > In fact I open a file (f : file declared as local var) in a > subroutine, read the file entirely to memory, but do not close it > again, I now see.

Files don't get closed automatically unless your entire program shuts down. > And/or as the files opened repeat, will I only end up with the number > of different file names, or a number equivalent to the number of calls > to the subroutine? Every time you open a file, you get a new file handle, separate from the last. -- Rob _______________________________________________ Delphi mailing list -> [email protected] http://www.elists.org/mailman/listinfo/delphi
