I sometimes copy a 40 GB tree structured directory to my laptop so I have access to the mostly PDF data files contained in it. This data contains much private and personal information so I obviously do not want it accessible if my laptop is lost or stolen. Is there any way of very securely encrypting this single folder and all its subdirectories and files? My thought is to have it normally encrypted but be able to open it prior to using an application like Paperport to access the files.
