how to open a folder within Powershell
Use the Invoke-Item cmdlet, or its alias: ii.
PS> ii c:\windows # open the windows directory in windows explorer
PS> ii c:\book.xls # open book.xls in Excel
PS> ii . # open the current directory in windows explorer
For Powershell and cmd compatible way ( and I think the most common way):
start .
start c:\
To open the current folder within the powershell type:
PS>> explorer.exe $(pwd)
