Is there an easy way to obtain the size of a drive?
(ie is there some function call that will return a drive's size/capacity)

Also is there a function to obtain the free space available on a disk drive??

Have you had a look at the Win32 help file. It has a function for GetDiskFreeSpace() and also has help topic for GetDrive type also. See if that helps. I hope you are talking about D3??

Use DiskSize and DiskFree:

  Showmessage(IntToStr(DiskSize(0) div 1024) + ' Kbytes capacity.');
  Showmessage(IntToStr(DiskFree(0) div 1024) + ' Kbytes free.');

DO NOT USE DISKSIZE AND DISKFREE!
They only support partitions with less than 2GB.

Comp is a 64-bit integer type and will support disks
up to 9,223,372,036,854,775,807 Byte.

Here's a simple solution:

  cmpDF, cmpDS, cmpDU: Comp;
  dwSPC, dwBPS, dwNFC, dwTNC: DWORD;

  GetDiskFreeSpace( PChar( chDriveLetter + ':\' ), dwSPC, dwBPS, dwNFC, dwTNC );
  cmpDS := Comp( dwSPC ) * dwBPS * dwTNC; // disk size
  cmpDF := Comp( dwSPC ) * dwBPS * dwNFC; // disk free
  cmpDU := cmpDS - cmpDF;  // disk used, huh?

I use Delphi 6 personal and I've tried it both ways, the API and DISKSIZE and DISKFREE. I have two 10 GB partitions and it seems to have no problem with it.
