Discover Drive content across all users in the domain

Index and search files stored across every user's Drive using a delegated service account, surfacing documents by content and metadata.

Who it is forIT, compliance, and knowledge management teams needing to surface documents domain-wide.

The problem

Documents are scattered across individual Drives, making it impossible to answer basic questions like 'who has a version of this file?' or 'where is this project spec?' without asking each user directly.

How it works

  1. Maintain a list of active users with Drive enabled.
  2. Impersonate each user with the service account and page through their files with the Drive API.
  3. Index file metadata and, if needed, fetch file contents for text search or classification.
  4. Aggregate results into a searchable index with references back to the owning user.

What changes

You gain a reliable, up-to-date map of all user-owned content, making discovery and compliance checks practical at scale.

The trap in this one. Drive API's files.list call is subject to eventual consistency: files recently created or moved may not appear immediately when impersonating a user. If you run discovery jobs on a tight schedule, you will miss documents that have not yet propagated across Google's backend shards. This leads to gaps that are silent—no error is thrown, but the file is simply absent from the results. Always account for this lag, and re-scan recent changes, especially after high-volume migrations.

Questions people ask

Does this pattern let me see files in Shared drives?

Only if the user being impersonated is a member of that Shared drive. You must enumerate both user Drives and Shared drives explicitly.

Is there a way to reduce API quota usage?

Yes: use the 'fields' parameter to limit returned metadata, and batch requests where possible. However, full content search will always be resource intensive.

Want this built?

This is a pattern we run in production. We will set up the delegation and build this on top of it — $500 per hour, most of it working the same day.
