Find duplicates synced from Google Drive on Mac
Google Drive for Mac syncs files to your disk where they can pile up as duplicates. Here's how to find them.
Google Drive for Mac (the desktop client) mirrors your Drive contents into a local folder, and over time that folder accumulates the same duplicates your Drive has on the web. Files you uploaded twice, copies you made of shared documents, exported Google Docs saved next to their originals.
Two paths
The native way: Google Drive web + Finder
You can dedupe on the web first:
- Open drive.google.com in a browser.
- Use the search box:
is:duplicatedoesn’t exist, but searching by filename and sorting by size catches obvious pairs. - For local files, open the Google Drive folder in Finder (usually
~/Library/CloudStorage/GoogleDrive-<email>or~/Google Drive). - Sort by Size, eyeball duplicates, verify with Preview.
- Move duplicates to the Trash. Google Drive syncs the deletion to the cloud (it goes to Drive’s Trash for 30 days).
The web side is limited and the local side is manual. For a few hundred files this is fine; for tens of thousands it’s not.
The Dupe way
Dupe scans the local Google Drive folder the same way it scans any folder.
- Download Dupe and open it.
- Click “Add Folder” and select your Google Drive sync folder.
- If you have streaming mode enabled (My Drive only available online), switch the files you care about to “Available offline” first so they’re local for Dupe to hash. Alternatively, only scan the “Mirrored” sections.
- Click “Scan.”
- Review duplicate groups and move the redundant copies to the Trash. Google Drive syncs the deletion.
A few Google Drive specifics:
- Google Docs, Sheets, and Slides files in your local folder are tiny
.gdoc/.gsheetshortcut files, not the actual documents. Dupe will hash those small files like any other — they’re rarely duplicated since each one points to a unique URL. - Exported PDFs, Office files, and images stored alongside Google Docs are full files and are where most duplicates live.
- Shared drives: deletions you make from a Shared Drive folder affect everyone with access. Be careful.
Safety:
- Trash-only on your Mac, plus Google Drive’s own 30-day Trash on the web.
- Google Drive cache and metadata folders are excluded.
- System paths are excluded.
- Byte-identical matching only.
For most users, the biggest wins come from old upload folders and copies of Shared Drive content that were dragged in years ago.
