Most of us are sharing a computer with many people. Sometimes we have many files that we don't want to share with others or even let others know about it. What will be the first option that'll come to our mind? Hiding the file. But if you choose "Show hidden and system files" in "Folders Option" your files will be visible to whomever using the computer. Else store it in secondary storage devices like floppy or CD or USB drive and carry with you. You can't depend on secondary storage devices as they can fail at any time.

You can try encrypting your file, hide its type and even file names or extensions. I am suggesting you a software that was distributed with "Computers Today" few years back. It is called "Cryptalite" and decrypting one is called "Decrypta Lite" conceived and distributed by Odyssey softwares, Chennai. Don't know whether it is available for downloads now or even developed further, but the version I have / suggest is really useful and more than enough for us.
Click here to download the software. (Zip, 1.31 MB)

CryptaliteThe best part of this software is that you can either install as regular one to access through Start Menu or just access the exe file directly without installation. Unzip the files to a folder. You can either install or simply create "Short cut to the desktop" for both Crypta & Decrypta Lite.

Encrypting the files:

1. Double click the "Crypta Lite", choose the source file/folder/directory tree, you need to encrypt.

2. Enter & confirm your password, click "Encrypt" and it is done.

3. The encrypted files will be stored with an extension of *.oaf

4. If you had chosen the "Hide File Name" option, the original file names won't be visible. Instead it will be renamed as file01.oaf, file02.oaf....

5. Remember the password, as there is no other way to recover the files once encrypted unless you have a copy / back up in another folder.

Decrypting the files

1. Double click the "DCrypta Lite", choose the encrypted source file/folder/directory tree, which had to be decrypted.

2. Enter your password, click "Decrypt" and it is done.

3. The option "Delete the source file" is self explanatory and better choose this option to avoid duplication of files in different formats.

If you find this process little lengthy or cumbersome, you can try Lock folder.... which will be discussed sometimes in another article.
