Method CopyFile

CopyFile(string, string, bool, int)

Copies a file from a source path to a destination path. This method uses low-level file streams instead of File.Copy (which uses Kernel32.CopyFileEx internally) to make it more compatible with file system virtualization methods which often(at least 2 of them) forget to hook them
