If the -folder option is used the from_path and to_path arguments are taken to be names or paths of folders (which must not include embedded spaces, although files within the folders may. See above for wide-character filenames). All files in the from_path folder are encrypted into the to_path folder. The to_path folder is created, if required, and the files inside it are overwritten.

No file extension is required, so this option is suitable for folders in the %PMLUI% hierarchy, but you must be careful not to encrypt non-PML files.
