MEO lets you encrypt files on your computer, send encrypted emails, and decrypt files. To encrypt a file, click on the Encrypt files button after you first start MEO. You can create a self-decrypting file with the click of a button, as well as set the crypto algorithm.
Setting the password is as simple as setting up an online account. Type it once, and then type it again to confirm. Sending encrypted emails is also a simple process. Attach your file to an email and send.
Decrypting files involves selecting the file and typing the password. MEO will export the file’s contents to whichever folder that you specify, while keeping the original encrypted file.

You will want to read the articles on the TrueCrypt website because they have some good information about how to use the program and what it can do. The TrueCrypt interface looks pretty straightforward. Create your volumes, add your files, and mount your disk.
