I installed Samba on my Pi B+ and am mapping the file system under MS Windows. I have a spare TB USB drive so I have a lot of unused space and my Pi is essentially a file server. You can edit dump1090 and piaware files in notepad.

I also installed CUPS so I can send text files directly to the printer from the Pi.
