By default, all ORB Applications available at this website, support Portable Mode.
This means they work normally as any other app and save data to the normal home folder ( /home/alex for example ), with two exceptions:
1- If an App is running from a USB drive or external HDD ( or any device in /media ), Apps will save their data/configurations into a sub-folder called portable_home
2- If a user manually creates the folder portable_home in the same folder of the .orb file
