The new Google Photos detect duplicates when you are uploading photos to your account. Google Photos app can scan your photo library and offer you to delete similar photos for you to free up a storage space on your phone .
If there are already duplicates in the cloud, Google Photos should give a function to search out all duplicates and delete them. This actual duplicate detection can exactly detect files of the same content but in different file names, different upload dates, upload by different clients, upload from different local devices, etc.
A frequent inquiry we ran across in our research was “How does Google Maps detect duplicate photos?”.
I discovered Google Photos has identical duplicate detection, where if you have uploaded photos to Google Photos already, it will not re-upload the same photo (each photo file has a unique “Hash” that allows us to determine this).
Moreover, does Google Photos delete duplicate photos when uploading?
One frequent answer is, if the file names of your photos are different and they are reside in different folders of your hard disk, then the Google Photos will still recognize the duplicates and remove them from the upload queue. Photos are precious memories and all of us never want to ever lose them to hard disk crashes or missing drives.
Using a new phone, new computer or reformatted computer (reinstall/upgrade OS, photos backup app, etc.) may also generate duplicated photos. Bugs can also create duplicate photos in your Google Drive.
