How to encrypt and password protect data files and folders on your PC.

Updated on October 29, 2011

What is Encryption & Password Protection?

Encryption is altering (a file, for example) using a secret code so as to make it unintelligible to unauthorized parties.

Password protection refers to giving a secret series of characters that enables a user to access a file, computer, or program.

The password helps ensure that unauthorized users do not access the file, computer or program.

Ideally, your password should be something that nobody apart from you could guess.

In practice, most people choose a password that is easy to remember, such as their name, kid’s name, pet’s name or their initials.

This is unwise and makes it relatively easy to break into most password protected computer systems, files or programs.

Safeguard Your Most Sensitive Information

Safeguard your most sensitive Information with a password from FileShield.

FileShield lets you easily encrypt and decrypt specified files and folders using just one password. Once locked, these files and folders cannot be deleted or moved.
The files are stored locally on your computer in a secured folder which only you can lock and unlock by entering your unique password. Just drag and drop files you want to protect into the secure folder.

Why Encrypt or Password Protect Files?

Why would you want to encrypt or password protect your data?

Well lets just say if you have very sensitive data (like your name, address, credit card number, PIN etc)

on your computer which is connected the Internet, then it might just be a wise idea to protect such data.

If you still have any doubts as to why you have to do this perhaps looking at the cyber crime statistics below, might help change your mind.

There are many stories today of Identify theft, and the number of such cases are growing.

A little deterrence like encrypting or password protecting your files is a vital first step in stopping such crimes, otherwise any nosy and Internet savvy geek could be accessing your personal data.

Ways to Encrypt & Password Protect Files

There are several ways to encrypt and passwords protect data files and folders on your PC.

Some of which are:

• Using your computer’s operating system (OS) built in encryption file system like windows file encryption .

• If you have Vista installed you could use one of vista’s security feature called Bitlocker.

• Third party encryption software.

Each method has its advantages and disadvantages.

The main advantage of using your computer’s OS security feature is that you do not have to download or install any additional software. However using a built in data encryption from your pc’s operating system still leaves you vulnerable.There is software abundantly available on the Internet to circumvent this particular method of securing your data. Also

• This type of encryption is based on your user profile's name and password.

• You must export your certificates and private keys in the event that your user profile becomes inaccessible for some reason.

• You can't share your encrypted files with others in an encrypted form since the encrypted files are only accessible by your user profile.

• Finally if you are logged in, your encrypted files become accessible.

On the other hand using third party software means downloading (sometimes purchasing) & installing additional software.

My favorite and recommended method is to use a third party encryption software utility.

There are many available on the Internet including TrueCrypt, Kruptos 2, AxCrypt, and Cryptainer.

I would recommend Truecrypt (get Truecrypt from

      Hi, I am munsif ali, from pakistan. I found above literature about encryption very helpful and found that windows vista/windows2000/and linux have feaures,

      It has cool features which enable you to drag-and-drop your files into an encrypted folder.

      But there is another security feature i.e. digitally signing files. I followed a windows xp demo, and digitally signed files of my hard disk, but still there were almost 3000 files which were not digitally signed. I selected programmes files and checked them wether these were digitally signed, my windows xp told me that none of the programme files were digitally signed, despite following the demo instructions. so I myself signed all the programme files, as we also have a programme file of internet. As I am new to pc, there fore , learning every system file and folder and the language it contains has become my greatest hobby.

      I suggest that , it should be upto me to create at least 5 to 6 barriers in form of security passwords for programme and system files.
