Compound File

The CompoundFile object represents the in memory representation of a Diffgram Compound File. This is a file that may contain 1 or more child files with different media types and configuration.

Most of the methods within the compound file object just modify the object in-memory. That means that no changes are actually stored on diffgram until you call either the upload() method for a new compound file. or the update_all() method for an existing compound file.

🚧

Adding/Removing Files on an already uploaded compound file is not yet supported.

Once you call the upload() method for a new compound file. You cannot modify the number of childs withing that compound file. However you can still modify the ordinal and other metadata of the compound or child files and then call update_all() to persist this changes on the Diffgram Platform.

New versions of the SDK and Diffgram Core will support adding and removing files soon.
