Mini-Example 2:
This setting optimizes the contiguous file allocation size for the file system and can be especially useful for disk intensive applications. Open up your registry and go to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem
Create a DWORD value named 'ConfigFileAllocSize' and set the value to '200' (in hex) or 512 (decimal)
