To remove files, mark the check box next to each file you want to delete, and then press the "Delete Files" link.  The system will search your website, and if the files you have checked for deletion are not linked elsewhere on your site Memberize will delete the files.  Files that are displayed or linked somewhere in your site are not deleted to prevent inadvertent loss of content and/or bad links in various pages or Newsletters.  In these cases the reference to the file (usually in a Web Page or Newsletter) must be removed or you will not be able to delete the file from the Quota Summary page.
