Type   Default Value   Read Only   Description
Long N/A Yes The total number of bytes of metadata held in the file.



When you view a file in Windows Explorer you see only the file data and the size of the file data - never the size of the metadata associated with that file.

The Length property holds the number of bytes of data for all metadata associated with the file. If you add this to the size of the file you will get the total number of bytes of disk space used by the file.

The Field Length is the same value as you would obtain by iterating through every metadata stream in the file and summing the lengths of each of these items of metadata.
