You can encrypt a directory, aka folder, on a Microsoft Windows system so that it's contents can't be accessed by others even if they boot the system with an alternate operating system from a CD or USB flash drive or remove the drive and put it in another system, so that Windows file permissions that might otherwise apply can't be bypassed. To encrypt a folder and its contents, right-click on the folder within the Windows File Explorer and choose Properties then click on the Advanced button and then click on the check box next to "Encypt contents to secure data". You will be asked to confirm that you wish to proceed with the change to the folder's attributes. Proceed, applying the changes to the folder, its subfolders, and the files within it.
