How much free disk space do I need to have in order to transfer videos to my portable device?
The amount of free space needed depends on the length of the OverDrive Video title that you wish to transfer to your device. One hour of mobile video is approximately equal to 200MB. Note that if you are using OverDrive Media Console v2.1 (or newer), the Transfer Wizard will alert you if you do not have enough storage space on your device to accommodate the files that you are attempting to transfer. Depending on your portable player, the Transfer Wizard may allow you to delete files on your portable player in order to make room for the files you wish to transfer.
