These directories can be used for any purpose in the instruction of the course. An instructor can put files in this directory for students to copy into their area and run, or homework assignments for students to look at or get.
Students can put their files there for the instructor to look at but no one else.
Below each section of a course, the directory structure will consist of a RF and WC subdirectory. The WC directory is where a student may place a file but will not be able to see anything that is there. Only the instructor will be able to look at, copy or erase any files in the WC directory. The student will only see the homework directories for the courses they are registered. The student will have to move into the directory they need by using the cd command.
