Like NTFS, exFAT can pre-allocate disk space for a file by just marking arbitrary space on disk as "allocated". For each file, exFAT uses two separate 64-bit fields in the directory: the valid data length (VDL), which indicates the real size of the file, and the physical data length.
The Transaction-Safe Extended FAT File System (TexFAT), TexFAT provides similar functionality to TFAT using the exFAT file system as the base file system instead of FAT. . Introduced with Windows Embedded CE 6.0, it is sometimes referred to as TFAT as well, which can lead to confusion with the original TFAT described a
A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...
PC DOS 1.x file attributes included a hidden bit and system bit, with the remaining six bits undefined. At this time, DOS did not support sub-directories, but typically there were only a few dozen files on a diskette. The PC XT was the first PC with an IBM-supplied hard drive, and PC DOS 2.0 supported that hard drive with FAT12 (FAT ID 0xF8 ...

A basic data partition can be formatted with any file system, although most commonly BDPs are formatted with the NTFS, exFAT, or FAT32 file systems. To programmatically determine which file system a BDP contains, Microsoft specifies that one should inspect the BIOS Parameter Block that is contained in the BDP's Volume Boot Record .
MFS – TiVo's Media File System, a proprietary fault tolerant format used on TiVo hard drives for real time recording from live TV. Minix file system – Used on Minix systems; NILFS – Linux implementation of a log-structured file system; NTFS – (New Technology File System) Used on Microsoft's Windows NT-based operating systems
The exFAT filesystem kernel exploit that led to the 9.00 jailbreak [21] also affected PS5 firmware up to 4.03, however due to additional protections on the PS5 it is not possible to use this to softmod the PS5. The PPPoE kernel exploit that led to the PS4 11.00 jailbreak [22] also affected PS5 firmware up to 8.20, and is not known to softmod ...
