I also use the Backup/Restore method. Backup, with whatever complexity you choose (full customisations or not etc) on your PC, copy .sqz to flash drive or CD etc, restore the .sqz on your laptop. This feature puts in a date for me too using the 'generate file name' tick box, so I get <project_name> yyyy-mm-dd hh-mm-ss.sqz
When I return I do the reverse.
It all works a treat and avoid any mistakes of missing a file or 2.
