Components
Each big file provider is an XPCOM component. The mail compose code uses the nsIMsgCloudFileProvider.idl interface to talk to the big file provider. The big file providers then use their own API to talk to their servers. This communication is specific to each provider. The general flow is authentication of the user, followed by uploading of file contents, and retrieval of a link to the shared file. This link is then included in the e-mail sent to the mail recipients.
There is also UI to provision accounts, and UI to control account settings. This UI is specific to each provider.
