What?
It would be nice, if there would be the possibility to read and write files to the clients filesystem but heavily restricted by size and location. There should be only one directory which can be written and read by java. Also there should be a restriction on the filesize (e.g. < 100mb)

Why?
Implementation examples:

• Log data to disc for better development support
• Write statistical data to disc which could be read by another program.
• An external tool could create an interface to select the soldiers loadout. The data would be written to the disc and the a3 java library could read this to provide the selected loadout. (network would be better, see link below)
