I have iPython Notebook through Anaconda. I accidentally deleted an important notebook, and I can\'t seem to find it in trash (I don\'t think iPy Notebooks go to the trash).
If you are running on Jupyterlab on linux like me. What I did is went into command prompt and went to my trash folder.
Trash directories on linux are typically
/home/$USER/.local/share/Trash
or
If you deleted something as root (e.g. deleted a file using Nautilus invoked via gksu), it is at
/root/.local/share/Trash
I ended up changing directories to /home/$USER/.local/share/Trash/files and my deleted notebook was there! depending on how you access your backend you could also try /home/jupyter/.local/share/Trash/
ps If you are having issues changing directories from Trash to files due to permissions dont forget to become root:
sudo -i
and the move to your files from there.
Best of luck,
