When a file is accessed, the directory must be sequentially searched until a match is found. For file names shorter than 16 characters in length, one file name record is required but the entire file is represented by three 32-byte directory records. This is called a directory file set, and a 256 MB sub-directory can hold up to 2,796,202 file sets.
File Allocation Table (FAT) is a file system developed for personal computers and was the default filesystem 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.
Password-aware operating systems should not hide password-protected files from directory views, even if this bit may be set. The password protection mechanism does not depend on the hidden attribute being set up to including DR-DOS 7.03, but if the hidden attribute is set, it should not be cleared for any password-protected files. 2 0x04 System.
FatFs is a lightweight software library for microcontrollers and embedded systems that implements FAT/exFAT file system support. [1] Written on pure ANSI C, FatFs is platform-independent and easy to port on many hardware platforms such as 8051, PIC, AVR, ARM, Z80.
exFAT supports files up to 127 PB. exFAT is the factory format of all SDXC cards, but is incompatible with most flavors of UNIX due to licensing problems. NTFS supports files up to 16 TB . NTFS is the default file system for modern Windows computers, including Windows 2000, Windows XP, and all their successors to date.
FAT (including exFAT) is brute force, you want to find a file, in a full directory of 256MiB, you have to search one by one. And there are 3x as many directory records, because to get to that number, it assumes 3 directory records per file, and you have to look at at least two for every file in there. It will take forever.

The native file systems of Unix-like systems also support arbitrary directory hierarchies, as do, Apple's Hierarchical File System and its successor HFS+ in classic Mac OS, the FAT file system in MS-DOS 2.0 and later versions of MS-DOS and in Microsoft Windows, the NTFS file system in the Windows NT family of operating systems, and the ODS-2 ...
