    - library(filesex): Extended operations on files

Availability::- use_module(library(filesex)).(can be autoloaded)

[det]directory_file_path(+Directory, +File, -Path)

[det]directory_file_path(?Directory, ?File, +Path)

True when Path is the full path-name for File in Dir. This is comparable to atom_concat(Directory, File, Path), but it ensures there is exactly one / between the two parts. Notes:

In mode (+,+,-), if File is given and absolute, Path is unified to File.
Mode (-,-,+) uses file_directory_name/2 and file_base_name/2
