Something I do which I find handy... I created a shortcut (right click, create shortcut) to the folder.
Then I placed that shortcut on my desktop.
Everytime I make a AHP change.... I change the name of the file. My ahx files are named by date, then letter. The 2nd change [if made today] would be named: 27jun07B
Before I walk away from my PC when done making changes, I open the folder on my desktop, right-click and copy the newest ahx file, then paste a copy to a flash-drive.
Ok...... I have a complete back-up Home Automation PC too. I use
BVC and have no intentions of having "down-time".
