Why can't I export a large file to my iXpand Flash drive?

iXpand Flash drives that are less than 64GB are formatted with the FAT32 file system, which has a 4GB file size limit.  If you have a iXpand flash drive that is smaller than 64GB, you can reformat it to the exFAT format which will allow any size file up to the size of the drive.  

Make sure you backup any files you want to save from the iXpand Flash drive before reformatting.
