If neither of the -folder or -pmllib options are used the from_path and to_path arguments are taken to be single file-names or paths (which must not include embedded spaces). The to_path file is created or overwritten, as appropriate.

To encrypt a single file with one or more spaces in its name, move it into a folder without spaces in its name, and then encrypt the contents of that folder with the -folder option. See above for wide-character filenames.
