Good morning all.  
I am running node-red in docker and want to share a text file outside of docker.  
In the docker compose file I did

> volumes:  
> - ./node\_red\_data:/data  
> - /home/server/docker/shared:/sharedfolder

I then placed a mytext.txt in the "/home/server/docker/shared" folder.

My assumption was/is that I would then be able to access the "/sharedfolder' within node red but when I try to write data to a text file I get the following error

`"failed to append to file: Error: ENOENT: no such file or directory, open '/sharedfolder/mytext.txt'"`

Writing to data to a /data/test.txt file works without a problem.  
Am I accessing the folder/file incorrectly?

The error suggests you are trying to add to an existing file. Does it already exist?

**[Edit]** Oh I see you have said that you have put a file there. Are you sure you have named it correctly, I see you have said

which is test.txt not mytext.txt.

Otherwise I don't know. I prefer to avoid docker whenever practical.

Hi [Paulf007](https://discourse.nodered.org/u/Paulf007),

I access my files on my host PC using Bind mounts, that should solve your problem ?

Hello Paul,

I had the same issue with access or create files/folders on my NAS drive .. I made a small write-up on how to bind your NAS Shared-Drives to docker [here](https://discourse.nodered.org/t/write-node-on-synology-nas/88430/9)

I hope it helps

Good morning all.

Thank you for all the feedback , I did some further reading as suggested and the solution seems to be that you need to "link" the folders within the /data/ folder so your docker compose should look like this.

```auto
volumes:
- ./node_red_data:/data
- /home/server/docker/shared:/data/sharedfolder

```

Then before you deploy the container create the folder 'sharedfolder' within the "node\_red\_data".  
So you will have "/node\_red\_data/sharedfolder" on the real world.  
I sort off expected for docker compose to do this but I am in no way an expert here and are just fiddling until I get it right 😉  
I have tested this, and it works. If you create a file in NR the file will be created in the " /home/server/docker/shared" directory , the "/node\_red\_data/sharedfolder" folder will remain empty.  
Hope this will help someone later.
