solution files arrangement
<p>my C# .NET solutions files are a mess.
i am trying to find a way of get things in order.</p>

<p>i tried to put all close files together in the same folder i creating for that purpose. for example i put interface, abstruct class &amp; all their inherited classes at the same folder.
BTW - when i do that i need to do "using" to the folder name for i can use those classes in other files. - also a mess i guess...</p>

<ol>
<li>there is an elegant way of doing things more clean and not a list of files that i very confusing?</li>
<li>its a good idea of lets say - open a abstract class file and add - i think its called - nested classes for all the classes derived from it?</li>
<li>side-Question: there is a way of tell the solution to automatically set the folder-usings above every class i create?</li>
</ol>

<p>thank u! </p>
