How To Encrypt Windows Files

TrueCrypt is a popular solution for those who want to encrypt Windows files and folders. Why encrypt Windows files? Privacy is a major factor at home and at the workplace. In addition, as more and more people use portable computers, the risk of losing valuable data increases. The thought of photos, financial information or other sensitive files falling into the wrong hands is terrifying and poses a huge security risk for companies whose employees work on the road. You need to encrypt Windows files in order to keep your privacy in-tact.

You can install a TrueCrypt volume in a single directory of a hard drive, an entire partition of a hard drive, or on a USB stick. The TrueCrypt software performs on-the-fly encryption, which means it encrypts and decrypts files as you open and close them, without any additional interaction on your part. Files are decrypted and stored in RAM (memory), meaning no decrypted files are ever stored on the hard drive itself.
