DriveInfo.AvailableFreeSpace Property
.NET Framework (current version)
Indicates the amount of available free space on a drive, in bytes.
Assembly: mscorlib (in mscorlib.dll)
| Exception | Condition |
|---|---|
| UnauthorizedAccessException | Access to the drive information is denied. |
| IOException | An I/O error occurred (for example, a disk error or a drive was not ready). |
This property indicates the amount of free space available on the drive. Note that this number may be different from the TotalFreeSpace number because this property takes into account disk quotas.
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); } } } } /* This code produces output similar to the following: Drive A:\ Drive type: Removable Drive C:\ Drive type: Fixed Volume label: File system: FAT32 Available space to current user: 4770430976 bytes Total available space: 4770430976 bytes Total size of drive: 10731683840 bytes Drive D:\ Drive type: Fixed Volume label: File system: NTFS Available space to current user: 15114977280 bytes Total available space: 15114977280 bytes Total size of drive: 25958948864 bytes Drive E:\ Drive type: CDRom The actual output of this code will vary based on machine and the permissions granted to the user executing it. */
