Get-PSDrive

Updated: April 21, 2010

Applies To: Windows PowerShell 2.0

Gets the Windows PowerShell drives in the current session.

Syntax

Get-PSDrive [-LiteralName] <string[]> [-PSProvider <string[]>] [-Scope <string>] [-UseTransaction] [<CommonParameters>]

Get-PSDrive [[-Name] <string[]>] [-PSProvider <string[]>] [-Scope <string>] [-UseTransaction] [<CommonParameters>]

Description

The Get-PSDrive cmdlet gets the Windows PowerShell drives in the current session. You can get a particular drive or all drives in the console.

Get-PSDrive gets the following drives:

-- Windows logical drives on the computer, including drives mapped to network shares.

-- Drives exposed by Windows PowerShell providers (such as the Certificate:, Function:, and Alias: drives) and the HKLM: and HKCU: drives that are exposed by the Windows PowerShell Registry Provider.

-- Drives that you create by using New-PSDrive.

Get-PSDrive does not get Windows mapped drives that are added or created after the Windows PowerShell console is opened.

Parameters

-LiteralName <string[]>

Specifies the name of the Windows PowerShell drive.

The value of LiteralName is used exactly as it is typed. No characters are interpreted as wildcards. If the name includes escape characters, enclose it in single quotation marks. Single quotation marks tell Windows PowerShell not to interpret any characters as escape sequences.

Example 1

C:\PS>get-psdrive

Name       Provider      Root
----       --------      ----
Alias      Alias
C          FileSystem    C:\
cert       Certificate   \
D          FileSystem    D:\
Env        Environment
Function   Function
HKCU       Registry      HKEY_CURRENT_USER
HKLM       Registry      HKEY_LOCAL_MACHINE
Variable   Variable
X          FileSystem    X:\

Description

-----------

This command gets the Windows PowerShell drives in the current session.

The output shows the hard drive (C:) and CD-ROM drive (D:) on the computer, the drives exposed by the Windows PowerShell providers (Alias:, Cert:, Env:, Function:, HKCU:, HKLM:, and Variable:), and a drive mapped to a network share (X:).

Example 2

C:\PS>get-psdrive d

Name       Provider      Root
----       --------      ----
D          FileSystem    D:\

Description

-----------

This command displays the D: drive on the computer. Note that the drive letter is not followed by a colon.

Example 3

C:\PS>get-psdrive -psprovider filesystem

Name       Provider      Root
----       --------      ----
C          FileSystem    C:\
D          FileSystem    D:\
X          FileSystem    X:\
Y          FileSystem    \\Server01\Public
Z          FileSystem    C:\Windows\System32

Description

-----------

This command displays all of the drives that are supported by the Windows PowerShell FileSystem provider. This includes fixed drives, logical partitions, mapped network drives, and drives that you create by using New-PSDrive that are mapped to the file system drives.

This example shows that drives created by New-PSDrive have the name of the mapped location in the value of the Root property. Windows drives just have the root of the drive letter.

Example 4

C:\PS>if (!(get-psdrive X)) { 
    new-psdrive -name X -psprovider Registry -root HKLM:\Network 
}
else { write-host "The X: drive is already in use." }

Description

-----------

This command checks to see whether the X drive is already in use as the Windows PowerShell drive name. If it is not, the command uses the New-PSDrive cmdlet to create a Windows PowerShell drive that is mapped to the HKLM:\Network registry key.

Example 5

C:\PS>get-psdrive -provider filesystem

C:\PS> get-psdrive -provider filesystem

Name       Provider      Root
----       --------      ----
C          FileSystem    C:\
D          FileSystem    D:\
X          FileSystem    X:\
Y          FileSystem    \\Server01\Public
Z          FileSystem    C:\Windows\System32

C:\PS> net use
New connections will be remembered.

Status       Local     Remote                    Network

Description

-----------

This example compares the types of file system drives that are displayed by Get-PSDrive to those displayed by using other methods. This example demonstrates different ways to display drives in Windows PowerShell, and it shows that the drives created by using New-PSDrive are accessible only in Windows PowerShell.

The first command uses Get-PSDrive to get all of the file system drives in the Windows PowerShell console. This includes the fixed drives (C: and D:), the mapped network drive (X:), and two Windows PowerShell drives (Y: and Z:) that were created by using New-PsDrive.

A "net use" command, which displays Windows mapped network drives, displays only the X drive. It does not display drives that are created by New-PSDrive. It shows that the X: drive is also mapped to \\Server01\Public.

The third command uses the GetDrives method of the Microsoft .NET Framework System.IO.DriveInfo class. This command gets the Windows file system drives, including drive X:, but it does not get the drives created by New-PSDrive.

The fourth command uses the Get-WmiObject cmdlet to display the instances of the Win32_LogicalDisk class. It returns the C:, D:, and X: drives, but not the drives created by New-PSDrive.

The last command uses the Get-WmiObject cmdlet to display the instances of the Win32_NetworkConnection class. Like "net use", it returns only the X: drive.
