The above scheme can be viewed in Acronis DiskEditor program in the view
as FAT folder mode. As you can see above, test.txt corresponds to two folder
elements. The lower line indicating Short Name value in the drop-down list on
the left and the uppercase name (TEST.TXT), and the upper one indicating Long
Name value in the list and 041h in the Ext/Prefix field indicating that a file’s long
name took one additional folder record.
3.6 Folders and Subfolders
Above we described the structure of the root folder in FAT32 file system that
contains file information: names, attributes, and some other.
A root folder may contain records corresponding to subfolders. A root folder
together with subfolders form the folder tree of the file system.
FAT represents a subfolder similar to a file described by a parent folder re-
cord, and consists of a set of the same folder elements as a root folder.
The very first element of a subfolder is a self-reference under «.» pseu-
donym. This reference provides the number of the first cluster of the
given folder. It is followed by an element referring to the parent folder
under «..» pseudonym. This reference allows to find the beginning of the
parent folder. At that cluster, with zero number, is specified the root
folder.
