About this tag
The FAT file system is a legacy file system used on older Windows versions like Windows XP and on removable media such as USB drives. In the WindowsForum.com community, discussions about FAT often involve troubleshooting issues with autorun.inf files on USB drives formatted with FAT, as seen in a thread about adding AutoPlay entries on Windows XP Service Pack 3.

These posts highlight that FAT is still encountered in scenarios involving compatibility with older hardware or software, and users may need to understand its limitations compared to modern file systems like NTFS or exFAT.
