How to Encrypt a Folder

To password protect your files and folders in Windows, you need to use a third-party program because most versions of Windows do not have built-in method of encrypting files and folders. In this guide I will be highlighting all the steps to successfully encrypt files and folders in most Windows distributions.

It is important you create a backup of non-password protected files before password protecting your documents. This is really important in the event when the password is lost and you need to access your documents.

Tips to consider when encrypting or password protecting files and folders

There is no absolute file protection. There exist many tools, utilities, and instructions on how to break the most common encryption types and passwords on files. The protection methods I will discussing will definitely protect your files from most of the users who might be trying to access them without your permission. For sensitive data use a proven commercial software to protect data and files.

You should consider backing up all your files, even those protected by passwords. This is because a password protected file or folder can still be deleted. The other option is to use a program that protects files from being deleted by requiring a password to do so.

Always back-up a copy of the non-password protected files and folders. This is important in case you forget the password. Attempting to break the password can take a lot of time and there is no guarantee it will be successful in the end.

In case you are unable to select the “Encrypt contents to secure data” option and it’s also grayed out, then you are likely running a Home edition of Windows.

Other tips for protecting your files and folders in Windows

Files and folders less frequently used should be password protected by creating an archive of built-in using a compression tool. The advantage of this is that when creating an archive you’re required to encrypt the contents by providing a password.

Windows ME and Windows XP come with their own compression utility which can be used to compress and password protect files.

Both Windows Vista and Windows 7 include a compression utility but password protection for the compressed files is not possible without the use of a third-party software tool.

When a file is compressed, users can still view a listing of the files in the compressed file. If you want both your file names and the contents to be hidden, move all the files into a single folder and password protect that folder.
