How to Find and Delete Duplicate Files in Google Drive

Google Drive is an excellent cloud storage platform, but because it shares your 15GB of free storage space with Gmail and Google Photos, it can fill up very quickly. Over time, it is common to accidentally upload the same documents, photos, or video files multiple times, creating a clutter of duplicate files that consume your valuable storage quota.

Unfortunately, Google Drive does not have a native “Find Duplicates” button. However, there are still highly effective manual and automated methods to track down and remove these redundant files.

Method 1: Search for “Copy of” in Google Drive

When you duplicate a file within Google Drive itself (by right-clicking and selecting “Make a copy”), Google automatically appends the words “Copy of” to the beginning of the new filename. If you have done this frequently, finding these files is very straightforward.

1. Open Google Drive in your web browser.
2. Click on the search bar at the top of the screen.
3. Type "Copy of" (including the quotation marks) and press Enter.
4. Google Drive will display all files that contain this exact phrase.
5. Review the list. You can select multiple files by holding down the Ctrl key (Windows) or Command key (Mac) while clicking on them.
6. Press the Delete key, or click the trash can icon in the top toolbar to remove them.

Method 2: Sort by File Size to Spot Duplicates

Often, the biggest culprits eating up your storage are duplicate videos or large PDF presentations. By sorting your entire Google Drive by file size, identical duplicates often appear right next to each other in the list, making them easy to spot.

1. Open Google Drive.
2. In the left-hand menu, click on Storage (located near the bottom, just above your storage quota indicator).
3. This view displays every file in your entire Drive, automatically sorted from largest to smallest.
4. Scroll down the list. If you have uploaded the same 1GB video twice, you will see two identical files with the exact same file size listed consecutively.
5. Right-click the duplicate file and select Move to trash.

Method 3: Use the Google Drive Desktop App (For Advanced Users)

If you have thousands of files and manual sorting is impossible, the most efficient method is to sync your Google Drive to your local computer and use a dedicated duplicate finder application.

1. Download and install Google Drive for Desktop.
2. Sign in and choose to Mirror files (which downloads them to your local hard drive) or stream them. Mirroring is better for this specific task.
3. Once your files are accessible via Windows File Explorer or macOS Finder, download a reputable third-party duplicate finder tool (such as CCleaner for Windows, or Gemini 2 for Mac).
4. Point the duplicate finder application at your Google Drive folder.
5. The software will scan the folder, identify identical files based on their hash (not just their name), and allow you to bulk-delete the duplicates.
6. Because Google Drive for Desktop is syncing these changes, the duplicates will automatically be deleted from your cloud storage as well.

Remember to Empty the Trash

When you delete a file in Google Drive, it is moved to the Trash folder and continues to consume your storage space for 30 days. To instantly reclaim the space, click on Trash in the left sidebar, click the “Empty trash” button in the top right corner, and confirm the deletion.
