Is it possible to exit several scripts by unplugging a USB stlck safely?

Yes, e.g. with IfExist

I think the point is to automatically exit the scripts when the user "safely removes" the USB stick. Since AutoHotkey.exe would be running off the stick, "safely remove" will fail and FileExist will continue to report that the drive exists. What we need to figure out is how to detect when the user wants to "safely remove," so we can automatically close the scripts and allow the stick to be removed.

i actually never savely remove usb-sticks, so i never experienced this. Twisted Evil

althogh the WM_DEVICECHANGE message ( aka the link provided by Zippo()) ) looks promising, there is an maybe easier workaround:

1. the script on the usb-stick, that is launched, just copies another script to a temp-dir on the harddrive and launches this. And it exits right after that.
2. the script on the temp-dir checks the existance of the usb-stick. If the stick is removed, it will exit and delete itself (via a batch-file, if necessary).
