When you are done working with the folder, you need to lock it back. You can set up a hot key for quick access to the lock folder command, or enable the option to add the Lock/Unlock commands to the right-click menu of the folder, or use some other method that you find of most convenience, as described in the User's Guide of Folder Guard.
You can lock files with passwords, too! First, use the Protect - Add File command of Folder Guard to add the file you want to protect to its window. After that, the procedure of setting up a filelock is exactly the same as it is for a folderlock (see above).
Note that the password prompt to unlock the folder is shown only when you double-click on the folder on the Desktop, in the right pane of a Windows Explorer window, or in the standard Open/Save As dialogs. If you attempt to open the locked folder via a shortcut or a menu command, the Access Denied or a similar message would be displayed instead of the password prompt. This is a limitation of the current design of Windows that does not currently provide a way to programmatically display the password prompt in such situations. To overcome such shortcomings, you can use the hot key of FolderGuard to quickly unlock or lock the folder as needed, instead of double-clicking on the folder.
