How can i encrypt my pen drive

I am carrying a USB pen drive, which has many important files and folders. I need to protect it with a password so that any one can not be able to see what is there in my Pen drive. Could any one of you make me know how can i make it password protected ?

Well, the one and only way i can suggest you is a freeware called TrueCrypt. Its is a Free Open-Source Disk Encryption Software. It is an is an excellent utility that can password protect the USB flash drive / pendrives, your hard disk’s and other devices too. If you only need a small portion in your USB flash drive / pendrive that needs to be encrypted, you can do that too with ease using TrueCrypt.

It enables you to create a virtual encrypted disk within a file and mount it as a virtual disk, that can be accessed via a drive letter. Any file that is stored on this virtual drive is automatically encrypted on-the-fly, and can only be accessed while the drive is mounted with the correct password or key. TrueCrypt supports a variety of encryption algorithms, including AES-256, Blowfish (448-bit key), CAST5, Serpent, Triple DES, and Twofish.
