Espacio en disco

[ehawee]

Hola estoy haciendo una aplicacion de copia de seguridad en visual basic .net y quisiera saber como obtener el espacio libre que hay en una unidad seleccionada.Se que en visual basci se usa GetDiskFreeSpace k declaramos nosotros.

Alguien sabe algo¿?


Muchas gracias.

Aquí tienes un ejemplo

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
