Hi,

The behavior is correct. You can find necessary information in following documentation:

http://devnet.kentico.com/docs/devguide/defining_custom_ml_folder.htm

The default location of all libraries of a particular site is ~/<sitename>/media. You can customize the location by entering a path in Site Manager -> Settings -> Media libraries -> Media libraries folder.

You can enter the folder location in the following formats:

• physical path: e.g. c:\Libraries
• virtual path: e.g. ~/Libraries
• UNC path: e.g. \\<server name>\Libraries

Media library module is not adding site name into the path if you are using custom medial library folder location and neither is it described in our documentation. You can set different the media library folder for each web site or you can store all files into the same location. This is up to you.

Best regards,
Miroslav Remias.
