Why you may need to Lock a File or Folder?

There are many reasons why you may feel a need to lock a file or folder. The most common reason is that you share your computer with others. Alternatively, you want to safeguard your files or folders and prevent them from being accidentally deleted. Or if you believe your PC is at risk of getting hacked, someone might steal sensitive information from you.

Locking a file or folder can help you control access to the data and ensure that it is not modified or deleted accidentally or intentionally. It is also helpful in cases where you need to ensure data integrity is maintained.

Windows comes with a built-in option to lock a file or folder. The feature is known as File encryption. Encrypting a file or folder with Windows ties the encryption to your account. This means that when you are logged in, the operating system automatically decrypts the files for you. However, if someone logs in using a different account, they will not be able to access files that were encrypted using your account.
