Transfer ownership for ALL files in user's google drive - using google-api-java-client and the Drive SDK
We have a google corporate account and need to transfer ALL of a user's google drive files to another account in certain instances. We want to do what is described at the following link for "all files" but programatically via the latest Drive API http://support.google.com/a/bin/answer.py?hl=en&answer=1247799
We are currently using the following API version(s) below, coupled with domain wide authority delegation as described at https://developers.google.com/drive/delegation and are able to see a user's files, iterate over them etc.
- google-api-services-drive 1.14.2-beta
- google-api-client 1.14.1-beta
My question is this: it appears that the only way to change permissions is by fileId by fileId etc. Instead of having to traverse and iterate over an entire set of user's files, if we just want to transfer ALL of a user's files to another particular user: is there a way in the API to do this (ownership transfer for ALL files) rather than individual requests file/by file?
Also when transferring ownershisp, must the transferee be in the same @domain or can it be another @domain we manage? I read somewhere that you can only transfer to owners in the same domain. Does this still hold true? For instance we manage @myCompany.com and have our corporate account registered under that, however that shell account has several sub-domains within it. We would like to transfer files from users in the sub-domains to a central user in the @myCompany domain.
Answer
You need to change permissions file by file, there is no updateAll type of functionality at the moment.
You cant transfer the ownership to another domain's user. Ownership can only be transferred to another user in the same domain as the current owner.
