How to protect folder with password in Windows 10 and Windows 11
You can use Folder Guard to password-protect folder or protect folder with password. When a folder is password protected, the password must be entered before the folder can be opened:
To set up a folder lock with password, use the built-in Quick Start Wizard of Folder Guard that can direct you through the process of creating the folder password. Or, simply use the Lock folder with password command from Folder Guard menu. You can also modify the properties of an existing folder password, by clicking on the link with the short description of the password in the Locked screen of Folder Guard application:
When are setting up a new password for a folder, first you are prompted to specify the password itself:
Next screen offers you to select the desired properties of the folder password:
In most cases, the defaults should work just fine. Or, adjust the following options, if necessary:
Who can use this password:
Any local user
If you check this box, then any user who logs in to this computer through the desktop would be able to unlock the folder by entering the correct password. Note that if the user logs in to the desktop using a remote access tool such as Remote Desktop, such a user is still considered a local user.
Any network user
If you check this box, then any user who connects to this computer through the Network folder would be able to unlock the shared folder by entering the correct password you've set up. Note that in order to be able to connect to the protected folder from another computer via the Network folder, the protected folder must be shared first (or located within a shared folder), using the standard folder sharing procedure offered by Windows. If the protected folder is not shared by Windows, then this option cannot magically enable other users to connect to the folder via the network.
This password unlocks:
This option would give the user a full, unrestricted access to the folder after the user has entered the correct password.
If this option is selected, then the user would be able to see the contents of the folder and open the files from that folder for viewing, but saving changes back to the protected folder would be denied. Note that the Read-only access does NOT prevent other operations such as printing or copying the files to other folders; it only prevents saving modifications back to the protected folder.
Notify the user about the access granted
If this option is selected, then after the user enters the correct password, Folder Guard displays a message with information that either the full or read-only access is granted to the user. If this option is not selected, then no such message is displayed after the folder is unlocked.
Lock the folder when the Explorer window is closed
If this option is selected, then when the user closes the original Explorer or application window that was used to unlock the folder, the folder would be automatically locked without asking the user to confirm. If this option is not selected, then the user would see a message asking them to select whether the folder should or should not be locked after closing the window. This option has no effect on other Explorer or application windows that were not used to unlock the folder, even if such windows currently display the protected folder. It may not have effect also on the computers where the Windows option Launch folder windows in a separate process is enabled. In such situations, use the notification icon to lock the folders back.
Lock the folder when the screen is locked
If this option is selected, then when the user locks the screen by, for example, pressing the Win+L keys, or when the screen is locked due to a screen saver becoming active, Folder Guard will automatically lock this folder. If this happens, then when the user unlocks the screen and logs back on to Windows they will need to unlock the folder again, to continue working with it. If this option is not selected, then the folder remains unlocked when the screen is locked.
Clear Explorer history when this folder is locked
If this option is selected, then Folder Guard will attempt to erase the history information related to the protected folder that is kept by Windows Explorer. Note that this option does not remove all traces of the protected folder from the computer. Also, other applications may remember this folder in their own history lists.
How to unlock a password-protected folder
If you need to unlock a password-protected folder, in order to use the files it contains, click the Unlock button in the middle of the folder's window in File Explorer, and Folder Guard will show a password prompt. Enter the correct password, and Folder Guard will allow the folder to open as usual. If the password is incorrect, the folder will remain locked.
How to lock the folder back
When you are done working with the files in the protected folder, press the Lock button on the right of the title bar of the folder's window, and that would lock the folder, until next time you enter the correct password. You may also want to set up the password option that would automatically lock the password-protected folder back when you close the folder's window. With that option enabled, you would close the folder's window, and that would cause Folder Guard to immediately lock the folder.
Protecting documents with passwords
If you have sensitive documents, such as tax returns or financial records, and you want to protect access to them with a password, you could put such documents into one folder, and protect that folder with a password. Or, if you have several folders under the common parent folder, you would protect the parent folder with a password, and that would protect all its subfolders, as well.
