title: Free space size information
body: <p>I wanted to know, how can i find the free space available in a drive in windows using C++. I have a path of the directory as input and I wanted to know if this drive or this directory has enough space to save my data. Main constraint is I should use only C++, not the VC++ or any kind of other windows programing because this application has to interact in batch mode to other applications.</p>
