FAT32 is a file system used to organize data on storage devices such as hard drives, SSDs, memory sticks, microSD cards, and more. It is an extension of the previous FAT16 file system and is named after the fact that it uses 32 bits to store addresses in the file allocation table (FAT) . FAT32 was developed by Microsoft and was first introduced in 1996.

One of the main advantages of FAT32 is its compatibility with different operating systems and devices, including Windows, Mac, Linux, Android, iOS, game consoles, cameras, and more. This means that data stored on a FAT32-formatted device can be easily accessed on different platforms without the need for additional software or drivers. FAT32 is also simple and reliable, with less overhead and fragmentation than other file systems.

However, FAT32 has some limitations that may affect its usage. One of the most notable drawbacks is the file size limit, as FAT32 cannot store files larger than 4 GB. Another limitation is the security and permissions features, which are not as robust as those in other file systems like NTFS.

In summary, FAT32 is a file system used to organize data on storage devices, and it is known for its compatibility and simplicity. However, it has some limitations, such as the file size limit and lack of robust security features.
