FIX: Root Directory Structure In Fat32

In this guide, we describe some of the possible causes that might cause the root structure in fat32 and then we give possible solutions that you can try to get rid of this problem.

The FAT32 root concatenates a directory in the data area with files and a host of other such directories, allowing it to expand under such load. With fat32 data, the range starts here. data area. This is where some of the data files and directories are located, and they take up most of the data on our partition.

The number of sectors within the directory in a fixed specification.The root directory on surfaces and sectors of FAT12 walls and FAT16 is continuous.on disk. For non-root directories as well as for root directoriesThe FAT32 directory appears, the number of sectors is not fixed at all, the saved directorybased on the usual chain of clusters

There are different types of long dates andFor file aliases.


The article for the Filename alias says:

What sector is the root directory in?

The number of entries in which the root directory and directory region on disk can be obtained is obtained from the BPB in the shoe sector at offset 0X0011. Each entry for a file in the root directory consists of the first collection number assigned to that file, which can be used as an entry point for FAT.

What is the root folder for FAT formatted volumes?

The root directory of FAT12 and FAT16 volumes is allocated enough space at the beginning of the volume to actually store 256 entries pertag, which is the upper limit of the wide range of files and directories that may be required for root storage (no listings pre-allocated disk space or number limit on FAT32 root websites).

How are directories stored in FAT?

FAT uses a 32-byte pattern, called a directory entry, to perform these tasks. Directory entries are placed in the cluster area in the form of files. Its size can always be calculated by looking at the maximum number of entries (listed in the FAT boot sector, typically 512) and increasing it by 32 by (bytes per list entry).

Two values ​​are not used, i.e. entries can be made with or with thembits set without the bit are considered invalid. invalid Another combination whenin both cases, the volume label bits are set in the directory. If you do not scan the disktool, this is undoubtedly the best way to ignore the most important entries with an invalid attribute. Name=”cs”>
