Actually it might be possible to customise the Windows Explorer to suit your needs better.
It's possible to change the folder icon to any icon you like, have a look

About the rearranging I must admit I'm not sure since I'm a Windows XP user and not Windows 7. Assuming it's similar in both versions though, if you right click in a Windows Explorer window there would be a menu item named something like 'Arrange Icons By'. If you have some kind of auto-sort/auto-arrange enabled there, you could try disabling it to see if things improve for you.
