Why do you not think it's what you need? – Clemmer

Answer 1

To get the current working directory use working_directory(CWD, CWD).

To change the current working directory use working_directory(_, NewCWD).

Check here to see the manual entry for this predicate.

Tab completion is very handy in case directory names in the path contain space e.g. working_directory(_, '/home/research/Artificial Intelligence/prolog'). – Maier

If using working_directory/2 on Windows and the change will change both the drive and directory as opposed to same drive different directory, then you need to also call working_directory/2 a second time with just the drive letter to change drives. e.g. You are on C:\Users\Foo and need to change to D:\foo\bar then you will need to use working_directory/2 again just with the drive letter. working_directory(_,"D:/"). – Infiltration

Answer 2

very easy just open prolog on terminal and write working_directory(CWD,'NewPath').

Ex: working_directory(CWD,'/home/user/prologExerc').

Answer 3

To view the current directory use : pwd.

And to change it use : working_directory(CWD,'path_or_location').

Example : working_directory(CWD,'C:/Users/Student/Destop').

Remember to change the direction of slashes in the path name.
