Jupyter notebook files association missing in Pycha - jupyter-notebook

I have problem with missing association of Jupyter Notebook files in PyCharm.
There is a fix for that here:
Go to: Preferences | Editor | File Types
Click on Jupyter Notebook & add .ipynb to the file name patters.
Unfortunately it works only until I restart PyCharm. After that the association is missing again.

Where does Jupyter Notebook save files?

So I'm just beginning my programming/coding journey. I've downloaded Anaconda and made a shortcut for Jupyter Notebook on my desktop. I tried using my first file the other day, and I'm not sure where it's being saved to. Also, I basically don't want Jupyter to save any Notebook I do once I close the Notebook, unless I specifically save it myself - I just use it for 'working out' if you like.
Here is the image showing what I mean
Like, where is that untitled.ipynb file being saved? And, how can I adjust my settings in Jupyter Notebook such that these files aren't saved and are discarded automatically so I can use them as I describe just for 'working out'?
By default the ipynb files are stored to your user profile:
C:\Users\yourlogin
How to disable autosave has already been described here:
Turn Off Autosave in IPython Notebook
I don't recommend doing that.

error loading jupyter notebook permission denied: ipynb

I was working in a jupyter notebook until it froze. It wouldn't save or shut down so I restarted my computer. I launched jupyter notebook from an anaconda prompt, my folder directory opens per usual. When i tried to open the notebook from before, I get an error loading screen that says permission denied: (name of notebook).ipynb. I hit close and the notebook shuts down.
I checked the folder permissions, I have full control. I can create a new ipynb without any issues. I can open other notebooks without any problem in the same folder. I tried to run a trust notebook through the anaconda prompt and it says the notebook is missing.
I need to recover this particular notebook as it has all my work. Help! Any ideas? Thanks in advance.
I work in the anaconda prompt in an environment other than the root, so this answer using sudo chmod doesn't work for me.
I had possibly the same problem. In my case the problem was that jupyter notebook must have crashed or had some problem whilst autosaving.
As a result, in the folder where the notebook is saved there's a temporary file called ".~nameofnotebook.ipynb".
This file didn't show up in jupyter notebook, but only in the explorer. I deleted the notebook file and renamed the temporary file to delete the ".~" prefix. Make sure to save a copy of the notebook file before deleting anything in case your problem is different.
The renamed temporary file opens fine and none of my data was lost.
Change the name of the file and you are good to go bro..

How to change Users folders in jupyter notebook and jupyterlab?

I have a question about jupyter notebook and jupyter lab and anaconda?
Does someone knows how to change the users folder from User a to b as an example?
I mean like I have 2 users in my PC and I want to use my secondary users folder in jupyter notebook and jupyterlab instead of my primary user folder.
Thank you
Create custom launching scripts for each user. The working directory can be set for jupyter lab using command line parameters:
jupyterlab --NotebookApp.notebook_dir=<directory_name>
(or using Jupyter config).

Creating Folder Failed on jupyter notebook

When I click "New" to create text file,folder, and python3 file on jupyter notebook, it shows that "Creating File Failed" and "An error occurred while creating a new file". Could you please give me some advice about how to solve this problem ? The screenshot is attached. Thank you very much !
Some details: I use pip install jupyter to install jupyter notebook in Linux environment. You can see from the attached screenshot that there is a new icon near to the upload icon on the upper right, then I click the black upside-down triangle on the new icon, then I choose folder. This is the process in which I try to create a new folder on jupyter notebook.
Use the --user tag with pip
The reason you cannot create a folder is because you do not have permission. This could be that you are not a on the sudo list or that you are not the owner of the folder where you are trying to create a new folder.
You can potentially avoid these problems by removing your jupyter install and re-installing with the '--user' option. Be sure that you have configured a non root user with sudo privileges and that you are logged in as that user. Try the following:
pip uninstall jupyter
pip install jupyter --user
Run notebook as usual:
jupyter notebook
One more thing, be sure that you are trying to create a folder in your home directory. If you are user "Bob", make sure you are creating the folder in /home/bob/ You are the owner of this directory and should be able to modify it as you wish.

I have found reasons that I cannot create new folder/file on jupyter notebook. Reason is that I directly open jupyter notebook in the anaconda3 environment, that's incorrect! Intuitive description is that I should switch from /home/${USER}/anaconda3 to /home/${USER}/anaconda3/bin, because when I use whereis jupyter, I find that jupyter is under /~/bin directory. So, I have a try and succeed !

How do I set the save location of a session in Jupyter notebook?

I'm working with Jupyter Notebook version 4.1.0 and can't seem to manually select the save path.
How does one manually specify where a session is saved?
You can launch jupyter notebook from the command line from inside the desired folder path. This will set the current folder as the start of the directory tree in Jupyter.
If we already have a session running, we can select the option IPython Notebook (.ipynb), from the file menu, under the Download as option. After saving the Notebook to a desired path, we can open it using the method described above.
