For manipulating files on your ComQuest system, there's nothing easier than Windows' own Explorer. For users with an access level of 800 or above, Explorer is accessible directly from the File Maintenance sub-menu under the Utilities menu.
Keep in mind while running Explorer from within ComQuest, that ComQuest is still running on your computer. As such, you will not be able to delete or overwrite any files (data or program) that are still open.
For specific instructions regarding finding files, copying, deleting, restoring files, etc. from within Explorer, please refer to Windows' own help screens, accessible from within the Explorer program.
