Free Disk space bigger than 2 GB

[jaraen]

Hi all,

How can I know the free disk space on a drive when this quantity is bigger than 2 GB!?

The GetDiskFreeSpace API is limited to 2 GB.

Any suggestion? I work with VB6 under Win 98.

Thanx in advanced.

i dont think there's anything you could do, maybe get total disk size and subract use space

For over 2GB disks use the GetDiskFreeSpaceEx API Function:

Create a new project, and add this code to Form1:
Private Declare Function GetDiskFreeSpaceEx Lib "kernel32" Alias "GetDiskFreeSpaceExA" (ByVal lpRootPathName As String, lpFreeBytesAvailableToCaller As Currency, lpTotalNumberOfBytes As Currency, lpTotalNumberOfFreeBytes As Currency) As Long
Private Sub Form_Load()
    Dim r As Long, BytesFreeToCalller As Currency, TotalBytes As Currency
    Dim TotalFreeBytes As Currency, TotalBytesUsed As Currency
    'the drive to find
    Const RootPathName = "C:\"
    'get the drive's disk parameters
    Call GetDiskFreeSpaceEx(RootPathName, BytesFreeToCalller, TotalBytes, TotalFreeBytes)
    'show the results, multiplying the returned
    'value by 10000 to adjust for the 4 decimal
    'places that the currency data type returns.
    Me.AutoRedraw = True
    Me.Cls
    Me.Print
    Me.Print " Total Number Of Bytes:", Format$(TotalBytes * 10000, "###,###,###,##0") & " bytes"
    Me.Print " Total Free Bytes:", Format$(TotalFreeBytes * 10000, "###,###,###,##0") & " bytes"
    Me.Print " Free Bytes Available:", Format$(BytesFreeToCalller * 10000, "###,###,###,##0") & " bytes"
    Me.Print " Total Space Used :", Format$((TotalBytes - TotalFreeBytes) * 10000, "###,###,###,##0") & " bytes"
End Sub
