Why NodeJS fs module won't read or write to visible folder shared on the network?

[worknotalent]

Details

I shared a folder on my network through the use of Windows UI.

I'm able to access this folder and edit its content through the File Explorer but problems arise when I try to do the same programmatically. Any fs functions will work on the hoster machine but on any secondary device it won't.

I had to pass the hoster session credentials when I first tried to access the folder from the secondary device so I'm guessing this folder is invisible to NodeJS for the same reason but I'm not sure, and if so I don't know how to pass credentials to NodeJS to make network folders accessible to it.

Node.js version

20.12.0

Example code

node:fs:2342
return binding.writeFileUtf8(
^

@nodejs/platform-windows does Node.js support network drives?

[worknotalent]

Someone on StackOverflow suggested to use a package called node-cmd to update the credentials first and then use the fs function but it still fails for me :
import cmd from "node-cmd"
cmd.runSync(net use \\DESKTOP-${device} /user:${username} ${password});

Did you try escaping backslashes
\\DESKTOP-NAME\folder\test.txt

You cant use a smb/cifs share as path in node.js.
Mount that network share as local resource like drive X: or what ever you want, and use then x:/path/to/wher-ever-you-want-to-go.

Does node support nfs/linux network shares? No.
You have to mount the network shared resources as local medium/device, and use that in node.js

Does Node.js not support UNC paths on Windows? I was under the impression that any UNC path referring to a real file system (not an emulated file system or USB device or so) would work.
