How to find hard disk space (free) through c++ code?

HI,
Can anyone give me some idea?

Without interfacing a specific API, you could pipe the output from the system command into a file and read-in the disk space. For example:

[CODE=cpp]
// For Unix, Linux, BSD, etc.
system("df -hl [disk or mount point] > output.txt");

// For Windows/DOS
system("dir /-C [disk] > output.txt");

// Where [disk] could be: "C:", "/dev/sdb1", etc.
[/CODE]
Then you simply have to open the file "output.txt " and parse the disk sizes back in.

Use the system calls or API.
