Is it possible to open a Windows Explorer window from PowerShell?

Use:

ii .

which is short for

Invoke-Item .

It is one of the most common things I type at the PowerShell command line.

You have a few options:

• Powershell looks for executables in your path, just as cmd.exe does. So you can just type explorer on the powershell prompt. Using this method, you can also pass cmd-line arguments (see http://support.microsoft.com/kb/314853)
• The Invoke-Item cmdlet provides a way to run an executable file or to open a file (or set of files) from within Windows PowerShell. Alias: ii
• use system.diagnostics.process

Examples:

PS C:\> explorer
PS C:\> explorer .
PS C:\> explorer /n
PS C:\> Invoke-Item c:\path\
PS C:\> ii c:\path\
PS C:\> Invoke-Item c:\windows\explorer.exe
PS C:\> ii c:\windows\explorer.exe
PS C:\> [diagnostics.process]::start("explorer.exe")

Just use the Invoke-Item cmdlet. For example, if you want to open a explorer window on the current directory you can do:

Invoke-Item .

explorer .

$startinfo = new-object System.Diagnostics.ProcessStartInfo 
$startinfo.FileName = "explorer.exe"
$startinfo.WorkingDirectory = 'D:\foldername'

[System.Diagnostics.Process]::Start($startinfo)

Hope this helps

Single line command ,this worked for me

explorer .\
