Looking for any light tool for open *.sdf files?

SQL Server Management Studio works. I'm not sure what you mean by "light".

You can try SQL Server Compact Toolbox. Its really light. Just a 1 MB exe and no install required.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
