exFATfailisüsteemiga

exFATfailisüsteemiga is a term used in computing to refer to devices and data organized using the exFAT file system. exFAT, short for Extended File Allocation Table, was developed by Microsoft to replace FAT32 for high-capacity removable media. It is designed to handle large files and volumes while retaining broad compatibility across operating systems.

Key features include support for very large files and volumes (theoretical limits in the exFAT specification reach up to 16 exabytes for a single file and 128 pebibytes for a volume), 64-bit file sizes, and long names encoded in Unicode. It is optimized for flash memory such as USB flash drives and SDXC cards, offering fast access and minimal overhead on removable media. Compared with FAT32, exFAT removes the 4 GB file size limit and allows larger partitions, making it suitable for modern media.

In terms of compatibility, exFAT is natively supported by modern Windows and macOS systems, and has gained broad support in Linux through kernel implementations and user-space packages. Some older devices or specialized embedded systems may require updates or drivers to access exFAT-formatted media. exFAT does not include journaling or built-in file permissions like NTFS or ext4; security and access control are typically managed by the host operating system.

Common use cases for exFAT include USB flash drives used for transferring large video files, external hard drives used across multiple platforms, and SD cards used in cameras and camcorders that require volumes larger than FAT32.
