For Box, Dropbox, and Office 365 OneDrive SaaS apps, whenever there is a change at the folder level, API Data Protection gets notified about the folder only. In the case of Google Drive, API Data Protection gets notified for all files under the folder. For instance, when a folder is shared as public, all files under the folder automatically have public access. But apps like Box, Dropbox, and Office 365 OneDrive notify API Data Protection about the shared folder event only. API Data Protection needs to explicitly perform a retroactive ongoing scan on the folder to make sure all the files are updated, and policy processing is triggered for the respective file.
