Using Ubuntu 11.10, I accidentally deleted a file that was approximately 700 MB. I tried to find it in the in following locations, but couldn't:
/home/user/.local/share
/home/user/ <-- there was no folder .Trash
/home/user/Desktop/ <-- there was no folder .Trash
So where did .Trash go in Ubuntu 11.10 onward? I use the Gnome environment.
