B: Remove Working Directory

Remove the working directory.
Here the working directory on Unix-like platforms is assumed to be a directory vwrk in the home directory, and the working directory on Windows platforms is assumed to be C:\Users\ilma\vwrk.

1. First of all, see the files inside the working directory and confirm if they can be removed.

   	$ ls -la ${HOME}/vwrk/⮠		for Unix-like platforms (sh system) ($ is the shell prompt)
   	% ls -la ${HOME}/vwrk/⮠		for Unix-like platforms (csh system) (% is the shell prompt)
   	> dir C:\usrs\ilma\vwrk⮠		for Windows platforms (> is the cmd prompt)
   

   If you find there important files (Scheme source files, text files, data files, and etc.), please move them into a different directory, or take a backup.


2. When you have confirmed that the working directory can be removed, remove the working directory.
   [Caution!]
   If the following operation is performed, then the working directory and all the files in it will disappear.
   

   	$ rm -rf ${HOME}/vwrk/⮠			for Unix-like platforms (sh system) ($ is the shell prompt)
   	% rm -rf ${HOME}/vwrk/⮠			for Unix-like platforms (csh system) (% is the shell prompt)
   	> rmdir /S /Q C:\usrs\ilma\vwrk⮠	for Windows platforms (> is the cmd prompt)
   



3. Check that the working directory is removed.

   	$ ls -la ${HOME}/vwrk/⮠			for Unix-like platforms (sh system) ($ is the shell prompt)
   	% ls -la ${HOME}/vwrk/⮠			for Unix-like platforms (csh system) (% is the shell prompt)
   	> dir C:\usrs\ilma\vwrk⮠			for Windows platforms (> is the cmd prompt)
