Hi All, I'm sure most of you have a more sophisticated way to backup your work on the fly but I just wanted to share something with you. I have had hard disk crashes in the past so I was always afraid of it happening again in the middle of a project. I now use a "Sandisk Cruzer" flash drive plugged into a USB port. I have a customized toolbutton with the following line: ^C^CQSAVE FILEDIA 0 SAVE G:project_name.dwg Y FILEDIA 1 Now I just click on that toolbutton periodically and I have a backup which I can take to another computer at anytime. I hope this might help some of you. Let me know what you think. Al
