Google Drive is Google's file sync app that lets you store all of your files online alongside your Google Docs documents, and keep them synced with all of your devices.
Mark duplicate submissions before assigning document review.
Spot repeated files before you review a team's batch. Your folder shows flagged copies, and a results file shows where their matches live.
Prepare one PDF packet from sections linked for review.
Your reviewer gets a single PDF in the order you set, with the finished packet attached and linked on the project task.
