in a couple of days time i'm going to need to write some HUGE (5 or 6 Gb each) files to a usb drive. it's a san disk cruzer edge i can't remember which file system it uses. will it need some kind of formatting to accept such huge files, i heard something about certain drive types not being able to cope with individual files above 4Gb. if it does can someone just quickly explain what to do? will this formatting affect others drives i plug into my usb port in future?
