What is actually contained in a *.suo file?

Question

I've read the MSDN Article about Solution User Options files

The solution user options file is used to store user preference settings, and is created automatically when Visual Studio saves a solution.

But what sort of settings or information is considered a "user preference setting"? I have a weird issue with one of my Solution files I've received from another company and the only fix seems to be periodically deleting the *.suo whenever the problem occurs. Can't figure out what sort of information is actually stored there though. I know it's nothing important, but I'd still like to know and I cannot seem to find the answer.

Answer 1

Basically the suo file(i.e., Solution User Options) contains the information related to to a user level customization like breakpoints, bookmarks, Outlining, debugger watches etc.

Also note that if you delete the suo file then Visual Studio will create a new one.
