DriveInfo.TotalFreeSpace Property
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Gets the total amount of free space available on a drive, in bytes.
public:
property long TotalFreeSpace { long get(); };
public long TotalFreeSpace { get; }
member this.TotalFreeSpace : int64
Public ReadOnly Property TotalFreeSpace As Long
The total free space available on a drive, in bytes.
Access to the drive information is denied.
The drive is not mapped or does not exist.
An I/O error occurred (for example, a disk error or a drive was not ready).
The following code example demonstrates the use of the DriveInfo class to display information about all of the drives on the current system.
using System;
using System.IO;
class Test
{
public static void Main()
{
DriveInfo[] allDrives = DriveInfo.GetDrives();
foreach (DriveInfo d in allDrives)
{
Console.WriteLine("Drive {0}", d.Name);
Console.WriteLine(" Drive type: {0}", d.DriveType);
if (d.IsReady == true)
{
Console.WriteLine(" Volume label: {0}", d.VolumeLabel);
Console.WriteLine(" File system: {0}", d.DriveFormat);
Console.WriteLine(
" Available space to current user:{0, 15} bytes",
d.AvailableFreeSpace);
Console.WriteLine(
" Total available space: {0, 15} bytes",
d.TotalFreeSpace);
Console.WriteLine(
" Total size of drive: {0, 15} bytes ",
d.TotalSize);
}
}
}
}
