Thanks for clarifying, I thought the comment above was asking why it needed file access in the first place, not all file access.

At least the HHR had a functional rear-view mirror

How do you think torrents work? They basically just download a file, but from multiple people instead of a single server. It needs access to the file system so it can save the files.

Edit: my bad, misunderstood. I thought the comment above was asking why it needed file access in general, not all file access.

Aw man, not that their machines were really anything special, but my printing journey started with their rebadged wanhao duplicator i3. Monoprice printers somehow made even creality look expensive at the time!

Looks like this printer is a rebadged flashforge adventurer. Monoprice also sells a version. You might be able to find a version of the firmware from one of those companies and use it.
