Drive structure C:\NU\diskedit.exe One drive Partition on 3 logical areas (drives) - fdisk

Format D:

Create new files on D: C:\NU\diskedit.exe

Physical structure drive D:

View sections „Partition Table“

Partition Table 1/2

Partition Table 2/2

Logical structure drive D:

Boot Record

Root Directory

Corresponding FAT

Now, we delete „command.com“

FAT after delete „command.com“

Root after delete „command.com“

„Undelete“ – recovery FAT

Join files A1,A2,A3 -> A1

Join clusters in the FAT

New file A1

Data content of file “A1” after join
