How to Find Duplicate Files in Google Drive
Google Drive has no duplicate finder. Here is how to spot likely duplicates in the web app, confirm exact copies by checksum, and remove them without losing anything.

Quick Answer
Google Drive has no built-in duplicate finder. To find duplicates, search Drive for "Copy of" and "(1)" and sort the storage view by size. To confirm files are exact copies, sync the folder to your computer and scan it by SHA-256, or run rclone dedupe list --by-hash drive:, which compares Drive's own checksums without changing anything.
The first two methods take a few minutes and need nothing but a browser. They catch the obvious duplicates but rely on names and sizes, which can mislead: two files called report.pdf may hold different versions, and two differently named files may be byte-for-byte identical. Methods 3 and 4 compare file contents, so they find every exact copy regardless of name.
Why Google Drive Fills Up With Duplicates
- Uploading twice. When you upload a file that already exists, Drive can keep both. Unlike a computer, Drive allows two files with exactly the same name in the same folder.
- “Make a copy”. Copies of shared files are named
Copy of …and often outlive the reason they were made. - Sync conflicts. Drive for desktop and other sync apps keep both versions when a file changes in two places, usually with a number added to the name.
- Repeated migrations and backups. Moving a phone backup or an old laptop into Drive twice can double thousands of files at once.
Method 1: Search and Sort in Drive
Open drive.google.com and use the search box to list the names duplicates usually get:
title:"Copy of"
"(1)"
type:image
type:pdf- Search
title:"Copy of"to list copies made from other files. - Search
"(1)"(and"(2)") to find numbered copies created by repeated uploads and sync conflicts. - Narrow to one kind of file with
type:image,type:pdf, ortype:video, then switch to list view and sort by Name so files with the same name sit next to each other. - Before deleting, open the file details panel and compare the size and modified date of each pair. Same name and same size is a strong hint, not proof.
Method 2: Use the Storage View to Find Large Duplicates
If you are cleaning up to free space, start with the biggest files. Click Storage in the Drive sidebar (or open drive.google.com/drive/quota). Drive lists every file you own from largest to smallest, across all folders. Duplicated videos, disk images, and ZIP backups stand out quickly because the same size appears twice in a row.
Not sure two downloads are really the same? Download both and drop them into the free Find Duplicates tool. It checks up to 10 files (10 MB each) by SHA-256 in memory on our server, without storing them, and groups the ones that are exact copies. For one pair, the Compare Files tool gives a straight identical or different answer.
Method 3: Sync the Folder and Scan It by SHA-256
For hundreds or thousands of files, checking pairs by hand stops working. The reliable approach is to bring the files to your computer and compare their contents with a checksum. Two files with the same SHA-256 hash are identical; any difference in a single byte gives a different hash.
- Install Google Drive for desktop (Windows or Mac) and, in its preferences, set My Drive to Mirror files. Mirroring keeps real copies on your disk. In the default Stream files mode, files are downloaded on demand, so a full scan would pull your whole Drive down anyway and can be very slow.
- Let the first sync finish, then point a duplicate finder that compares by content at the mirrored folder (or just the subfolder you want to clean).
- Review each group, keep the copy in the folder where it belongs, and remove the rest. Deletions in the synced folder go to Drive's Trash.
Google Docs, Sheets, and Slides are not real files on disk
In the synced folder, native Google documents appear as tiny .gdoc, .gsheet, and .gslides shortcuts. They hold a link, not the document, so a checksum scan cannot tell whether two Docs have the same content. Check those by name, or export them (File → Download, or Google Takeout) and compare the exported files.
FolderManifest is one way to do the scan. It is a desktop app for Windows 10/11, macOS, and Linux that finds duplicates by exact SHA-256 content match: renamed copies are caught and two different files are never grouped together. You review the duplicate groups as a plan, approve what is removed, and keep a record of what changed. Files are read on your computer and never uploaded. It does not find visually similar photos, such as resized or edited versions of the same picture; for those, use a similarity tool (our duplicate photo finder guide explains the difference).
Method 4: rclone dedupe --by-hash (No Download Needed)
rclone is a free, open-source command-line tool for Windows, Mac, and Linux that talks to Google Drive directly. Google stores a checksum for every uploaded file, and rclone can compare those checksums without downloading anything. It is also the practical option on Linux, where there is no official Drive client.
After connecting your Drive with rclone config (this guide assumes you named the remote drive), list duplicate content without changing anything:
# List files with identical content anywhere in My Drive (changes nothing)
rclone dedupe list --by-hash drive:
# Limit the check to one folder
rclone dedupe list --by-hash "drive:Photos/2024"
# List files that share the same name in the same folder
rclone dedupe list drive:--by-hashgroups files by checksum, so renamed copies are found. Without it, dedupe only looks for files with the same name in the same folder, which Drive allows and other systems do not.- The
listmode reports and never deletes. Native Google Docs, Sheets, and Slides have no checksum and are not matched by hash.
Do not run rclone dedupe without a mode first
In its default interactive mode, rclone deletes identical copies without asking and only prompts for the files that differ. Always start with list, then add --dry-run before any mode that removes files, such as rclone dedupe newest --by-hash --dry-run drive:.
How to Delete Google Drive Duplicates Safely
- Check sharing before you delete. A copy that looks redundant may be the one a colleague or client has a link to. Open the share settings of each copy and keep the one others use.
- Keep the copy in the right folder, not just the oldest or newest one.
- Use Trash as your safety net. Deleted files stay in Trash for 30 days and can be restored. They only free storage once Trash is emptied, so wait until you are sure.
- Keep a record for work files. For client or team drives, note which copy you kept and which you removed. If you are archiving a whole Drive rather than tidying it, our guide to verifying a Google Drive backup shows how to prove nothing went missing.
Frequently Asked Questions
Does Google Drive have a built-in duplicate finder?
No. Google Drive has no button that finds or removes duplicate files. You can spot likely duplicates by searching for "Copy of" or "(1)" in file names and by sorting the storage view by size, but confirming that two files are truly identical needs a checksum-based tool.
Why does Google Drive create duplicate files?
The usual causes are uploading the same file twice and choosing to keep both copies, "Make a copy" on shared files, sync conflicts from Drive for desktop, and migrations or photo backups that ran more than once. Drive also allows two files with exactly the same name in one folder, so duplicates are easy to miss.
How do I find duplicate photos in Google Drive?
Type type:image in the Drive search box to list only images, then sort by name or size to spot repeated files. For exact copies at scale, sync the folder to your computer and run a SHA-256 duplicate finder, or use rclone dedupe with --by-hash. Edited or resized versions of a photo are not exact copies and need a visual similarity tool.
Can duplicate Google Docs, Sheets, or Slides be found by checksum?
No. Native Google Docs, Sheets, and Slides have no file checksum, and on your computer they appear as small shortcut files (.gdoc, .gsheet, .gslides) that only point to the online document. Compare them by name, or export them first (for example with Google Takeout) and then compare the exported files.
What happens when I delete a duplicate in Google Drive?
It moves to Trash, where it stays for 30 days before Google deletes it permanently. You can restore it from Trash during that time. Files only free up storage once they are removed from Trash.
Is it safe to use a third-party Google Drive duplicate cleaner?
Cloud cleaners need permission to read and delete everything in your Drive. Check who makes the tool, what access it requests, and whether it moves files to Trash or deletes them outright. Working on a synced local copy, or with rclone in list mode, avoids granting that access to a new service.
