A friend of mine uploaded multiple gigabytes worth of images to her Google Docs account and shared the collection containing them. Keep in mind that there are over 15,000 images that were in this collection. She provided a link to me and some others and we clicked it to see what it was. Upon clicking the link, the collection was immediately added to my "Collections shared with me." That was not what I wanted to do; I just wanted to view the list of the files.
The files all immediately showed up in my Google Docs account as Shared. They did not use any storage on my account, as expected, but they did greatly clog up my Google Docs - looking at thousands and thousands of image files mixed in with my own documents and files is just crazy. In addition, all of the files in that shared collection started downloading to my computer because of a Google Docs client application that I use.
I immediately tried to remove them from my account. I right clicked the shared collection under "Collections shared with me" and chose to Unsubscribe. It removed the entry from "Collections shared with me," but it did not remove any of the files from my account. So, I had over 15,000 unwanted images in my account with no way to delete them in bulk. Insane.
I attempted several things to delete them. I tried to search 'from:herus...@gmail.com' and that did return the items from that collection, but there was no way to delete them all. Choosing to select all only selected the first 50 displayed. If I selected more than 50 at a time, such as 200, and clicked to delete them, a server error occurred. There was no way I was going to delete them all manually like that. Another thing I tried was to have her unshare it and share it again; unfortunately, the files came back in my account. Basically, I am stuck with a ton of unwanted files in my account with no way to get rid of them.
Today, I wrote a Python script using the Google Data API to search out the files and delete them all individually. This is taking quite a long time and I don't know how effective it is. You can find my code here: http://privatepaste.com/5e0fe105a8
I think that it's completely unacceptable to add an entire collection of files to a user's account just by clicking a link. That sounds like a good way people can prank others, as it's very annoying. I think when a collection is shared, the contents of it should be displayed and there should be a button to add it to your own Google Docs account. This should not be automatic. In addition, there needs to be a way to delete all results for a search, a working way to unsubscribe completely from a shared collection, and the ability to see who has shared with you and remove all of their files from your account. I imagine the average user is not going to be able to write a Python script to solve these problems in Google Docs.
Please fix this; it's a very big flaw in Google Docs for me right now.
