A5 FAT, FAT32, NTFS, and exFAT are the most popular currently. Each of them has its own pros and cons.
Users are recommended to choose the format type corresponding to their needs. However, the latest exFAT
is not initially included in Windows XP. Win XP users can add support for exFAT by installing an update from
Microsoft at http://support.microsoft.com/kb/955704/. However, please note that the update kit is only for versions later than Win XP SP2 or SP3.
