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. 

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.
