Google Drive and Shared Drives, Duplicate files

[LeeC]

Hi,

Can anyone recommend a process or add-on that can find duplicate files in Google Drive and Google Shared Drives? We have a large amount of data and a cursory look indicates that there are duplicate files and this leads to different versions being edited by different people leading to inaccurate data. We can train the staff but we need to get to a point where we have consistent accurate data.
