      Header:DJIMediaManager.h
      Description:

      Refreshes the file list of the storage. If the current state is DJIMediaFileListStateReset, the media manager will try to fetch the complete file list.

      Header:DJIMediaManager.h
      Description:

      States of the file list in DJIMediaManager.

      Enum Members:
      DJIMediaFileListStateUpToDateThe file list is up-to-date: it is synchronized with the SD card in the aircraft.
      DJIMediaFileListStateIncompleteNew files have been generated since the last call of refreshFileListOfStorageLocation:withCompletion. Calling refreshFileListOfStorageLocation:withCompletion can synchronize the newly generated files and append them to the end of the file list.
      DJIMediaFileListStateResetThe file list is reset. The file list will be reset in one of the following cases:
      - Camera is disconnected.
      - SD card is formatted.
      - SD card is not inserted.
      - Error occurs when deleting files from SD card.
      In this state, sdCardFileListSnapshot will return nil.
      DJIMediaFileListStateDeletingdeleteFiles:withCompletion has been called and the operation is still in progress.
      DJIMediaFileListStateRenamingA renaming operation is in progress.
      DJIMediaFileListStateSyncingThe media manager is synchronizing the file list from the SD card.
