Do we know for certain that this will adversely affect CloudDrive (I too am planning on blowing through the million file limit easily with only 20mb chunks)? Reading through the api documentation V1-V3 the only issue seems to be below:
orderBy
A comma-separated list of sort keys. Valid keys are 'createdDate', 'folder', 'lastViewedByMeDate', 'modifiedByMeDate', 'modifiedDate', 'quotaBytesUsed', 'recency', 'sharedWithMeDate', 'starred', and 'title'. Each key sorts ascending by default, but may be reversed with the 'desc' modifier. Example usage: ?orderBy=folder,modifiedDate desc,title. Please note that there is a current limitation for users with approximately one million files in which the requested sort order is ignored. (string)
