Hi, I am trying to use the FreeRouting application for Windows and am getting a message that it is unable to read the dsn-file. It was working and then it just stopped and I'm not sure what I could have changed that would have made it stop working.

I can confirm that Freerouting fails to read this file with the following error log:

According to my quick investigation the DSN reader can't get the name of the network scope that is just after Net-(D16-Pad2).
When I looked into the file I couldn't see anything wrong with the file: the next name was Net-(D17-Pad2).

I suspect that it is related to the DSN file size, and the buffer sizes we use in Freerouting.

I don't know the fix yet, I just wanted to share the progress with you.

Alright, that was it, I just pushed a fix, I increased the buffer from 512k to 4M, and it seems like working.

You can try it if you download the SNAPSHOT build from here: https://github.com/freerouting/freerouting/releases/tag/SNAPSHOT

Looks like a cool project, by the way!
