FInding the hard disk storage capacity programmatically

How do I find out the storage capacity of my harddisk without using the OS functions like dir or ls?

Solution

  • On windows:

    Win32: GetDiskFreeSpaceEx

    .NET: DriveInfo

    If, for whatever reason, you still don't want to use those, you can send an IOCTL message direct to the disk driver.
