Hello,
I have just bought a 64 gb Sandisk flash drive and found I cannot save my 5.51 gb video, although it will save smaller videos. What is the upper limit to save a video on a flash drive?
I believe it is 4gb for FAT 32 which is what flash drives come formatted in. You are going to have to format your flash drive to NTFS if you want to save files bigger than 4gb.
