exFAT (Extensible File Allocation Table) is a file system optimized for flash memory such as USB flash drives and SD cards, that was introduced by Microsoft in 2006. [ 7 ] exFAT was proprietary until 28 August 2019, when Microsoft published its specification. [ 8 ]
Memory card readers, unlike smartphones, telephones and other devices, such as cameras and digital cameras, allow formatting in a file system other than FAT (FAT16, FAT32, exFAT) to NTFS in Windows, ext, ext2, ext3 in Linux or HFS, HFS + for Mac OS. Smartphones or other devices like cameras format them only in FAT.
In laptop and tablet computers, memory cards in an integrated memory card reader offer an ergonomical benefit over USB flash drives, as the latter sticks out of the device, and the user would need to be cautious not to bump it while transporting the device, which could damage the USB port. Memory cards have a unified shape and do not reserve a ...
NTFS 1.0 is incompatible with 1.1 and newer: volumes written by Windows NT 3.5x cannot be read by Windows NT 3.1 until an update (available on the NT 3.5x installation media) is installed.

File Allocation Table (FAT) is a file system developed for personal computers and was the default file system for the MS-DOS and Windows 9x operating systems. [citation needed] Originally developed in 1977 for use on floppy disks, it was adapted for use on hard disks and other devices.

Windows 7 also supports the newer exFAT file system. As the ReadyBoost cache is stored as a file, the flash drive must be formatted as FAT32, NTFS, or exFAT in order to have a cache size greater than FAT16's 2 GB filesize limit; if the desired cache size is 4 GB (the FAT32 filesize limit) or larger, the drive must be formatted as NTFS or exFAT.
Packages the flash memory, currently soldered in shipping smartphones, into a removable card form factor. Uses the SCSI command set including queuing. The electrical interface makes use of differential signaling , which enables high bus speeds and robustness under noisy conditions and reduced pin count (compared to parallel bus alternatives ...
