setfile errors

[ken gray]

i have a function that is monitoring file access in a directory. when a file is accessed it copies the name and time over to a text file. it works fine unless there are a lot of access events (like a massive copy process). when this happens i get this error.

"The process cannot access the file because it is being used by another process."

Is there a way to reliably to do this even for massive file triggers?
