To import files into the Media Library, files MUST exist on the physical file system where the Sitecore Web Instance Resides. Enter the full path to the folder containing the content and the parent folder in the media library to hold the files. If you choose file system then all files will be uploaded to the file system. If you chose database, all files will be placed in database. If you choose mixed we will attempt to put file in database, if fails we will try file system. if that fails will add to failed log.
