This section contains two sample media libraries, one for publishing images, the other for videos. The media libraries are created using the Media module. The module can be used to store any types of files, not only media files, while large file sizes are supported. Management of the libraries and files in them can be performed in CMS Desk - > Tools - > Media. Detailed information about the module can be found in Kentico CMS Developer's Guide - > Modules - > Media.
