The file system exFat also supports USB drives and files larger than 100 petabytes. ExFAT is supported by Linux, macOS, Chrome OS, and Windows, meaning it will work with the overwhelming majority of all computers you will ever encounter. You should probably pick exFAT If you don’t know which file format you need, or you don’t have any specific use in mind. (For example, you should run a full format to securely erase any sensitive data before disposing of or giving away a USB drive.) Since flash memory has a limited number of writes, you should avoid full formats unless it is absolutely necessary. A full format will overwrite the entire USB drive.


A quick format won’t actually wipe any data, it’ll just allow it to be overwritten. Format Options – You can choose between quick format and a full format.Volume Label – This is just the name of the drive.Leave it alone unless you have a specific need. Smaller units result in less wasted space, but at a mild performance cost. Allocation Unit Size – The allocation unit size is basically how the space on the USB drive is divided up.

They each have different properties that determine maximum file sizes, maximum storage volume, and operating system compatibility.
