Vanguard snapshot file names too long

[skybeing]

My Vanguard software is set up to take a snapshot from the camera every 10 second. The file names are really long numbers that don't seem to have any rhyme or reason.  Is there anyway to set up the file name with the date & time the snapshot was taken?  When I try to copy these files to an external hard drive or DVD, I get an error that the file names are too long.
