In August 2024, Microsoft released an update to Windows 11 preview builds that allows for the creation of FAT32 partitions up to 2TB in size. [42] The maximal possible size for a file on a FAT32 volume is 4 GB minus 1 byte, or 4,294,967,295 (2 32 − 1) bytes. This limit is a consequence of the 4-byte file length entry in the directory table ...
The partition type (or partition ID) in a partition's entry in the partition table inside a master boot record (MBR) is a byte value intended to specify the file system the partition contains or to flag special access methods used to access these partitions (e.g. special CHS mappings, LBA access, logical mapped geometries, special driver access, hidden partitions, secured or encrypted file ...
According to Microsoft, the basic data partition is the equivalent to master boot record (MBR) partition types 0x06 , 0x07 (NTFS or exFAT), and 0x0B . [2] In practice, it is equivalent to 0x01 ( FAT12 ), 0x04 ( FAT16 ), 0x0C (FAT32 with logical block addressing ), and 0x0E (FAT16 with logical block addressing) types as well.

The total count of reserved sectors is indicated by a field inside the Boot Sector, and is usually 32 on FAT32 file systems. [4] For FAT32 file systems, the reserved sectors include a File System Information Sector at logical sector 1 and a Backup Boot Sector at logical sector 6. While many other vendors have continued to utilize a single ...
Some MBR code loads additional code for a boot manager from the first track of the disk, which it assumes to be "free" space that is not allocated to any disk partition, and executes it. A MBR program may interact with the user to determine which partition on which drive should boot, and may transfer control to the MBR of a different drive.
In the late 1990s, Intel developed a new partition table format as part of what eventually became the Unified Extensible Firmware Interface (UEFI). The GUID Partition Table is specified in chapter 5 of the UEFI 2.11 specification. [2]: 111 GPT uses 64 bits for logical block addresses, allowing a maximum disk size of 2 64 sectors.
UEFI support in Windows began in 2008 with Windows Vista SP1. [22] The Windows boot manager is located at the \EFI\Microsoft\Boot\ subfolder of the EFI system partition. [23] On Windows XP 64-Bit Edition and later, access to the EFI system partition is obtained by running the mountvol command. Mounts the EFI system partition on the specified drive.
