Before we get into that, though, let’s talk a bit about how these programs work....

Who Should Use Quickoffice? Quickoffice’s largest advantage is its ability to edit Microsoft Office documents that aren’t stored on Google Drive. It can pull files directly off your phone’s internal memory. Before being bought by Google, the app supported many providers such as Dropbox, SugarSync, and others.

Symmetric Key Encryption Algorithms Symmetric key encryption algorithms rely on a secure password to act as the key. This is the oldest form of encryption. Symmetric keys form the basis of everything from combination locks to modern hard drive encryption. AES, DES, and Blowfish are all modern symmetric key encryption algorithms. Because symmetric encryption requires a shared key, the key exchange must be performed securely. While modern techniques like the Diffie-Hellmen key exchange permit exchanging a shared secret over insecure lines, it requires significant communication overhead to do so as well as shared trust between communications....

The most usual case may appear after you try to copy or back up a virtual machine....

Why is this so? Most older Android phones are using the USB block mode to connect to your computer. In this mode, the computer will see your phone’s SD card as a USB device and mounts it as one.
