In a .NET/C# project, one of my *.exe files has a corresponding *.duo file. (I didn't set up the build system.) What is it?
Somebody suggested it was something like a user preferences file for the debugger, possibly?

Did you mean .suo? That stands for Visual Studio Solution User Options.

Try searching in http://file-extension.net/

Hmm, I'd tried searching on a couple of those sites, which was apparently not enough.

I think it might mean database user options, because it seems to have some form of relation with Microsoft Access.

I can't seem to find any info on the file extension : http://filext.com/alphalist.php?extstart=^D
Additionally - it does not appear to be a valid Visual Studio file extension - are you using any 3rd party tools that might generate this? What are you using for source control?
