exFATformaati

exFAT, which stands for Extended File Allocation Table, is a file system developed by Microsoft. It was designed to overcome the limitations of previous file systems, particularly FAT32, while offering greater compatibility than NTFS. The primary motivation for exFAT's creation was to support larger file sizes and volumes than FAT32, which had a 4GB individual file size limit and a theoretical maximum partition size of 2TB (though practical implementations often limited this). exFAT addresses these limitations, allowing for significantly larger individual files and partition sizes.

exFAT is widely used on flash memory devices such as USB flash drives and SD cards, especially those with capacities exceeding 32GB. Its cross-platform compatibility is a key advantage; it is natively supported by modern versions of Windows and macOS, as well as many other operating systems and devices like digital cameras and game consoles. This broad support makes it a convenient choice for transferring large files between different operating systems without the need for third-party drivers or conversion utilities. While it lacks some of the advanced features of NTFS, such as journaling and file permissions, its simplicity and broad compatibility make it a popular choice for portable storage.
