I didn't explain myself properly... I wrote some deviceiocontrol code = for wme/w98 and it craches because createfile on vmm32.vxd (or whatever) = returns null. Getdiskfreespace works properly on my machine (then again, I have = 32k and 4k clusters...). Still, there should be a function that works on ALL windowses and that returns the cluster size. ---------------------------------- Peace and love, Tweety mi...@sy... - twe...@us...

Subject: RE: [GD-Windows] retrieving the cluster size on xp I'd bet some money on your source being the reason for crashing. The GetDiskFreeSpace API works fine for me on all flavours of Win32. I don't think you'll crash XP calling this function, it's your app. Generally, Win9x is much more forgiving when it comes to invalid memory accesses than the WinNT siblings. Wich is actually a good thing.
