How does Google Drive handle multiple copies of same file?

Google Drive does have some measures to prevent unnecessary duplicate files from appearing. Let’s look at them.

Does google drive upload duplicates?

Years ago, if you tried to upload duplicate files to Google Drive, your files would be uploaded and got filenames like this File (1), File (2) and so on, which could cause confusion and made it harder to organize files.

Now Google can skip duplicate uploads. When you upload a file to Google Drive, if you reupload the same file, or if there is already a file with the same name and format in your Google Drive, the duplicate copy will be detected and not uploaded. But there is an option called “Keep as separate file”. If you click it, the duplicate will be uploaded with filename like File (1).

Keep as separate file option

According to my tests, Google Drive can identify duplicate files only based on the filename and file format. The content isn’t taken into consideration. The identification and detection can still be improved. Also, the detection won’t work if you upload the same file to different Google Drive folders separately.

Why does Google Drive create duplicate files?

Some Google Drive duplicate files are created during upload. Also, Google Drive’s long-time desktop sync solution “Backup and Sync” could duplicate files sometimes, creating file copies with (1) in filename.

Does Google Drive create duplicate files after editing?

When it comes to multiple copies of the same Office file such as a Word document or an Excel spreadsheet, Google Drive will merge them and only keep the latest uploaded version (with the other versions being available for viewing and restoring). For example, to access the older versions of a document, choose to open it with Google Docs. In the menu bar, select File > Version history > See version history.

Does Google Drive detect and remove duplicate files?

Google Drive doesn’t detect the existing duplicate files in your account, less alone remove them.

How to stop Google Drive from duplicating files?

The Back up and Sync app may create duplicate files due to your settings. For such a case, a Google Drive user figured out a solution and shared it.
