Microsoft: Special Characters in Files or Folders Name Not Supported in WebDAV

If a file name or a folder name includes special characters like an ampersand (&), a plus (+), a percentage (%), and so forth, the files or folders will not show up or work in a variety of WebDAV connection methods. This is a known issue because those characters are reserved characters in HTML. The only solution is to rename the files and folders in order for them to show up.
