Hi Skippy742,
In windows XP the only reason you would see this error is if you were tryig to open a file before it has finished downloading, or if indeed you had not enough room on your hard drive to allow the file to open.
Check your hard drive space just to be sure, although you should get a notice when you are running low on diskspace!
I doubt very much if it has anything to do with mIRC per say. (Unless there is a bug in 6.13 that when you move from the default download directory it keeps a process alive or something!) One way to check this would be to close mIRC when the download completes, log off then back on and see if you can open the file then.
As a matter of interest, how soon after the download completes are you trying to open the file?
Regards,
Diz
