Exclude folder should be easy but not text file.
It is hard to separate non-shader text file without checking its content.

Yeah I'm not suggesting it prereads every txt file, I just think the one called README can be explicitly excluded, unless at some point we expect to have a shader named README. Which would be pretty stupid and very unlikely really.

here's a quickly thrown together patch

I'd rather only check if the filename is "README" and additionally insert a line like if (entry.children[i].isDirectory) continue;
Hardhacking the fact that we're using subversion is kinda stupid imo :D

looking into the code more the shaders actually append .txt when applied so anything that doesnt fit into the strcmp with .txt should be ignored

a better patch

Uhm, why not just only add the file to the shader list if a) it's file extension is .txt b) it's filename is not "README.txt"?

I assume that you are talking about the removal of the extension before the compare with readme?
Since the list currently shows just the name without the extension I left that removal in. I don't really care either way, so I'll defer to your expertise :)

We could use a different file extension for the shaders.

.cg is always a popular extension for Nvidia CG shaders
