Simple and straightforward usage of the google drive api to remove duplicates. (identical name/size of files)
I use the the "GoPro Quik" application to import videos/images and sync them automatically to my drive. The "Delete all" function from GoPro didn't work properly and I ended up with several copies of the same file. All those copies were happily synced to my drive and used valuable storage.
I was able to free-up 60gb in one run.
Note: Tested and used only for my use-case, so use on your own risk :) Refer: https://developers.google.com/drive/api/v3/quickstart/dotnet
Please let me know ff you know a better way to remove duplicates.
