The maximum size for a FAT32 directory is 65536 32bit entries. If you lost data by accident, free download EaseUS Data Recovery Wizard to undelete files, unerase and recover lost data, unformat disk, restore formatted or deleted hard drives, partitions under FAT 32 file system. Upper limit on number files in a directory? For FAT16 and FAT12, this extra step is needed to compute the special space allocated for the root directory. So use more clusters for this "file" just as you would with any other file. They lack "RootDirSectors", because FAT32 stores the root directory the same way as files and subdirectories, so RootDirSectors is always zero with FAT32. For older FAT32 drives the limits are 65,534 files in a single folder and max file size of 4 Gigabytes and 2TB of total space or all of disk space that was available or whichever is less. That means the maximum size of a direcotry (file) is 65,536 * 32 bytes, i.e. The root folder on a FAT32 drive is an ordinary cluster chain, so it can be located anywhere on the drive. 2,097,152 bytes. Finding the root directory and files Understanding open, close, read, write 2. A directory in the FAT filesystem is only a special type of file. The maximum number of files within a directory of a FAT file system is 65,536 if all files have short filenames (8.3 format). Maximum number of files in the root directory (FAT12/16; 0 for FAT32) 19-20 Number of sectors in the file system; if 2 B is not large enough, set to 0 and use 4 B value in bytes 32-35 below 21 Media type (0xf0=removable disk, 0xf8=fixed disk) I am trying to back them up to a modern external drive, with some success - but I would like to know what the practical limit is for number of files per folder, as well as number of files per volume. "FAT32 was introduced to overcome some of the limitations of FAT16. Project 3 You will create a user-space utility to manipulate a FAT32 file system image ...

Short filenames in 8.3 format consists of 8 characters plus optional a "." The cluster number of the root directory is stored at offset 0x2c of the FAT32 header and is usually cluster 2.The entry in the cluster map for cluster 2 contains the value 0x0FFFFFFF (end-of-clusters) if this is the only cluster for the root directory. The external drive is a 1TB USB3 and is freshly formatted to NTFS on a Windows 10 computer. 17­18Maximum number of files in the root directory (FAT12/16; 0 for FAT32) 19­20Number of sectors in the file system; if 2 B is not large enough, set to 0 and use 4 B value in bytes 32­35 below Long filenames are stored in 16bit UNICODE characters and only thirteen characters are stored per directory entry.

In addition, file allocation table mirroring can be disabled, allowing a copy of the file allocation table other than the first one to be active. The root directory of FAT12 and FAT16 volumes is preassigned enough space at the start of a volume to store 256 directory entries, which places an upper limit on the number of files and directories that can be stored in the root directory (there’s no preassigned space or size limit on FAT32 root directories ).
