This was handed to me recently. It isn't my code and I can't find the author... but it seems to work fairly well.<br>

Sorry, Jim and Coverdale. The code was bit excessive but I thought I'd throw it on the forum because it showed "last access time" too. And I thought it was kinda neat.<br>
<br>
I'll stick to the easy solutions in the future.<br>

Just to make things worse for you here Alt - the filesystemobject from the scripting library (vb6 - but works with 5) does all that and more...<br>

It's a cruel world. I must have been asleep at the keyboard. Thanks for the wake-up, Mike. <p> <br><a href=mailto: > </a><br><a href= Vorpalcom home page</a><br>Send me suggestions or comments on my current software project.

This thread is a great example of why threads shouldn't be closed -- we would miss the implied humor in our tech-world.<br>
<br>
But seriously folks... Coverdale may have closed the thread after seeing that Alt255's solution worked and missed out on a couple of good alternate solutions.<br>
<br>
good post!<br>

OK! I Give In!<br>

"Closing Threads" is a Defunct Idea and something that other, lesser, sites do.<br>
