I'm on windows 7 creating a desktop aplication in Visual C# 2010.
The error's produced here:

Code:
void Copymove(string file) 
{
 File.Copy(Environment.GetFolderPath(Environment.SpecialFold er.MyDocuments), "../../contenidos/" + file);
}
The exact error:
Access to the path 'C:\Users\Danie l\Documents' is denied.

I've already tried modifying the app.manifest...
