File sharing with ethernet shield?

I've searched a bit on google and haven't seen anything related to file sharing with Arduino so I'm not sure if it's even possible, but I'm not sure why it wouldn't be.

What I would like to do is pretty simple (in theory), I have an Arduino with an ethernet shield that I would like to plug into my local network, and from time to time I would like the Arduino to read a text file that is stored on a PC on the network.

Can this be done with Arduino or am I better off using a Pi?

Just about any web client example does that. That is what the internet is about. File sharing.

Here is mine in the playground.

It is up to you what you do with the file after that. Parse it or save it to a SD.
