Other streams may be used to represent item thumbnails or alternative data formats. The correct method to use depends on where the content is coming from and how large the contents of the item are. Simple item upload is available for items with less than 4 MB of content.

Multipart item upload allows you to upload both the contents of an item and provide metadata about the item in the same call. This is only available for OneDrive Personal. Upload from URL preview allows you to upload the contents of a file by providing a URL where the contents of the file can be retrieved.
