Thanks, that took care of that problem. :)

It is in a loop scanning the directory since there could be more than one
file I'm looking at. The only reason I am using ExAll is because it is the
newer function. I thought it was the better way to go although I haven't
used any of them before so I'm only guessing.

It looked like DateStamp was a lot easier. Wouldn't using the timer
device to get the current time add a lot of extra code?
