:When supporting computer systems the overseer(whether for business or volunteering purposes) becomes responsible for its protection and the efficient operation. In this case, the volunteer becomes the "caretaker" of this system, and deals with a lot of issues that are usually "hidden" or "ignored" by the users of the system. This is not to point the blame on the user, but to emphasize the human nature of '''"out of sight, out of mind"'''.  IT volunteers deal with many "behind the scenes" issues such as computer server backup, running benchmarks, Internet Security, application installation, and user documentation. Therefore, when users or instructors do not properly remove completed files from the computer system, it becomes yet another task that the computer administrator has to "deal with". In fact, the problem becomes compounded when the administrator is not certain whether or not the files are permitted to be removed, and may have to track-down the instructor to get permission to remove the file.
