Does not require Admin rights to open encrypted disk.

Encrypted Rohos Disk BrowserThe new version of Rohos Disk (1.18) includes new utility, Rohos Disk Browser. This enables you to open and view the contents of secret partitions on a USB drive on any other computer, even if you do not have administrative rights.

Rohos Disk can password-protect a portion of a USB flash drive, by creating a virtual encrypted partition. The partition is protected by a password, and can be opened on any computer. Now, even if you are in an internet cafe and have no administrative rights, you can still have read access to your secret partition with the help of the Rohos Disk Browser utility. This means that you can open any file and read any data. Naturally when you are at your home or office computer, you will still be able to work with your encrypted partition as usual.

On a strange computer you can always open your protected partition on the USB flash drive (in read-only mode) with the help of the Rohos Disk Browser utility. This makes it possible to open or copy only one particular file or directory, without granting access to every file.

This feature is enabled in a Rohos Mini Drive program – FREE and tiny USB drive encryption tool.
