A few weeks ago, files appeared in my Trash Can. I didn't really look into it and keep thinking it was just temporary files that I deleted myself while working.
But after a while, I opened those files and noticed that they aren't mine but come from my college computer, and she hadn't deleted it but just open it.
I first thought it was related to Google Drive or another cloud application, but she didn't put those file in any cloud service.
Since this make no sense to me, I hope you may have an answer. What could be happening, and how to avoid those file leaks (some can be sensitive since she's managing all billing.)
