High-level formatting is the process of setting up an empty file system on a disk partition or a logical volume and for PCs, installing a boot sector. [1] This is often a fast operation, and is sometimes referred to as quick formatting. Formatting an entire logical drive or partition may optionally scan for defects, which may take considerable ...
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.
If needed, it will install a bootloader such as SYSLINUX or GRUB onto the flash drive to render it bootable. [9] It also allows the installation of MS-DOS or FreeDOS onto a flash drive as well as the creation of Windows To Go bootable media. [10] It supports formatting flash drives using FAT, FAT32, NTFS, exFAT, UDF and ReFS filesystems. [11]

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 .
All of the Linux filesystem drivers support all three FAT types, namely FAT12, FAT16 and FAT32.Where they differ is in the provision of support for long filenames, beyond the 8.3 filename structure of the original FAT filesystem format, and in the provision of Unix file semantics that do not exist as standard in the FAT filesystem format such as file permissions.

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.
