I thought it behaved differently - however it seems that the default action chosen for dropping a file is more complicated than what you described: even in my user directory, it is not deterministic: I just tried dragging a file from my home directory to my desktop. It moves the file. When I drag it back, it copies it!
I thought about that, and discovered that if your /home/myuser is a symlink, nautilus will feature this strange behavior: drag and drop in the desktop from the home will move, drag and drop from the destop to the home will copy. Shall I reopen and leave this as a bug editing the description? -- Nautilus has poor usability w.r.t. the action choosen when dragging and dropping https://launchpad.net/bugs/82196 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
