I use Iomega Automatic Backup which basks up files each time they change: http://www.iomega.com/software/autobackuppc.html It backs up my DX4WIN and Writelog directories over the wireless network to another PC. I could have chosen to backup to a USB memory device or ZIP disk on the local computer too. 73 - Jim AD1C ===== Jim Reisert AD1C, 7 Charlemont Court, North Chelmsford, MA 01863 USA +978-251-9933, <jjreisert at alum.mit.edu>, http://www.ad1c.us
