\label{Portfolio_DeleteFile} The portfolio allows you to delete some files. Locked files (files that have been handed in as solutions to a problem) cannot be deleted. Subdirectories can only be deleted if they are empty. Enter the directory (See: Changing Directory \ref{Portfolio_ChangeDirectory}), delete the files if necessary (see below) and click \textbf{Delete Directory} to delete the current directory. To delete one or more files: \begin{enumerate} \item Check on the checkboxes next to the filenames you wish to delete. \item Once all files in the directory are checked press on the \textbf{delete checked files} button. \item A confirmation screen will appear. Make sure that the filenames are correct. Press \textbf{Continue} to delete the file, and \textbf{Cancel} to cancel the deletion of the file. \end{enumerate} File deletion cannot be undone.
