I have a San Disk 16GB Cruzer, I want a Flash Drive that will allow exe files to be installed to it so you can run the files off of the falsh drive on a computer without having to install the files to a computer. I talked to a sales representative at Best Buy and they said if I formatted it that I could do that because thats what they did and it works. Exactly what do I format it as: NTFS,FAT32, or exFAT? What’s the difference between them?
