LONG DESCRIPTION
    Windows PowerShell includes a set of cmdlets that are specifically
    designed to manage the items in the data stores that are exposed by Windows
    PowerShell providers. You can use these cmdlets in the same ways to manage
    all the different types of data that the providers make available to you.
    For more information about providers, type “Get-Help about_providers“.

    For example, you can use the Get-ChildItem cmdlet to list the files in a
    file system directory, the keys under a Registry key, or the items that are
    exposed by a provider that you write or download.

The following is a list of the Windows PowerShell cmdlets that are designed
for use with providers:
