Even if Windows comes along with a feature allowing you to hide a folder on a computer, it is not very reliable especially if it is an important folder. For this purpose, it would be better to use a program like MEO for peace of mind.
MOE is a software that can help you protect your files or e-mails. This is an easy tool for encrypting and decrypting files, but it uses a sophisticated algorithm to protect your confidential files. This software can protect both individual files and the entire folders it seamlessly integrates into Windows Explorer so that you can encrypt or decrypt your files via the right click context menu.
