Unfortunately, SanDisk has obviously not bothered in the product description should be noted that only the FAT file system is supported. This one has after charging, App-Install and configure Flash Drive and MicroSD unfortunately reformat itself find there an error message in the app appears (with a maliciously grinning Smiley)
Conclusion: The maximum file size is 4GB FAT thanks to what disqualifies the machine for HD movies.
SanDisk itself we learn that there is a firmware update for exFAT for Wireless FlshDrive with 64GB card, but who "only" buys the stick with the 32GB card does not get the exFAT update.
SanDisk I was used only well-made quality products in recent years - but this article is with its flowery praise without proper compatibility warning a joke that I did not expect from SanDisk.
