And while I was at it I'm now also working around the 2GB limitation on 95/98/ME. Marcel ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
Re: [ql-users] How Much Space Do I Have?
My system gives some very strange results. STAT dos1_ (153GB) is: 238221176/321669424 and returns 238221152/321669424 dos2_ (8GB) should be: 321744/16787488 and returns 238221168/321669424 It seems that dos2_ is reporting back the capacity of dos1_. I'm running the latest QPCII on XP Pro. Dos1_ is a SATA drive and dos2_ an old ATA.

Hm yes, W98, that's the clue. The Microsoft documentation to the function GetDiskFreeSpace mentions this: "Windows Me/98/95: For volumes that are greater than 2 GB, the GetDiskFreeSpace function may return misleading values. The function caps the values that are stored into *lpNumberOfFreeClusters and *lpTotalNumberOfClusters so as to never report volume sizes that are greater than 2 GB. On volumes that are less than 2 GB and that have more than 64 actual sectors per cluster, *lpSectorsPerCluster will be capped at 64 and the values that are stored into *lpSectorsPerCluster, *lpNumberOfFreeClusters, and *lpTotalNumberOfClusters will be incorrect. That is because the operating system adjusts the values so that computations with them yield the correct volume size with the capped *lpSectorsPerCluster." Yeah, great. Must wait for me to be in a really good mood to bother to work around this. Marcel ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm

Strange, my dos1 drive gives: C:\ 4193664/4193664 sectors Thats about 2GB while it should be 4GB free on a 6GB partition. All my partitions give exactly the same numbers, they all have more than 4GB free. Also QPAC2 Files reports 2048MB for both free and total numbers. My QPC2 (3.32/3.12) runs under W98SE.
