11.13 what is media? What is media reference? Local synchronization of media reference?

Media represents a variety of files, which are stored in data in a unified manner. When media is used, we call it reference to media, or media reference for short. When media is stored in data, large data files may be several MB or dozens of MB. It is not necessary to load these files into the memory each time you read and write media references. The performance consumption for reading and writing these big data files is very high.

_ MediaReference. SynchronizeFile ();

 

To obtain the complete local path of a media set, use the following method:
