After installing on an external drive can the drive be moved computer to computer, namely my PC and a couple of my laptops?
P.S. Wonderful program. I had more than one freeware stuff for years but seldom used them, but this program is extremely faster and more useable :).
I can suggest you to use Tools - Backup/Restore buttons. This way you can compress and save the Project with its settings and all downloaded files in a single file.
You can easily restore this project to any other Offline Explorer copy on another computer.
Another way is to use Portable Offline Browser version (it is the same as Offline Explorer Pro in features) but you can install it to USB drive and download files directly to it. You can plug in this drive to any other system and browse/download sites.
