I have a list of files. I want to calculate total amount of space required by these files. For that, I have to calculate folder size. After the calculation of total size of file; I want to know how much free space is available at the destination. Then draw 3D Pie Chart for Required and Available spaces. I'm using VC++ 2010 MFC application. so my questions are:
1. How to calculate size of folder without all recursion?
2. How to get destination drive space?
3. How to draw attractive 3D Pie Charts in VC++ MFC?
