What is Root Directory of USB – Root directory of USB refers to the main directory structure of a USB flash drive or external storage device. It is the “home” location of the drive, meaning every other folder or file is organized beneath it.
How the Root Directory Works
- Top-level access: When you open a USB drive, the first screen you see is the root directory.
- File system dependent: Whether FAT32, exFAT, or NTFS, the root directory is automatically created when the drive is formatted.
- Storage organization: All folders and files branch out from this root.
