Encrypting files helps prevent other users or hackers from viewing important files, individual or in a folder, but also prevent unwanted modifications. It is not a 100% protected file, especially if the software used to encrypt a file has bugs or vulnerability. It’s best to keep files in a user account in Windows that require users to logon, and never leave your computer unattended.
Antivirus and firewall software should be enabled to prevent malware or hackers from gaining access or modifying any important documents. Remember to keep the password safe whenever you use third-party software to encrypt files and folders. Please note that not all encryption software protects the file from delete action so it’s best to create a new user account for other users to use in Windows or other operating systems. Keep a backup of your system and password-protect the backup so you can restore the unencrypted files anytime you need it.
Shadow Copy in Windows 7 and Vista keeps an older version of the file, if you don’t want others to see the old copy, you need to remove it from being copied by Shadow Copy (also known as Previous Versions feature in Vista and Windows 7)
