Hide Folder Ext — Hide, lock, and password-protect folders on external drives
Hide Folder Ext is a unique program that hides folders on external drives. While all other folder hiding applications are intended to hide folders on internal drives, Hide Folder Ext lets you hide folders on external drives (external HDD, flash drive, pen drive, etc) or removable media (Secure Digital cards, CompactFlash cards, Memory Sticks).
Hide a folder on an external disk and it will be invisible even if you connect this disk to another computer!

Hide Folder Ext exploits undocumented features of Windows file systems.
We strongly recommend that you unhide your folders before running any disk or file system utilities on the disk. Although our tests show no problems with Windows disk-checking or defragmentation utilities, you should always remember that running third-party disk utilities may damage your hidden and even visible files on this disk. We strongly recommend that you back up your sensitive files on a regular basis.
