-------------------------- EXAMPLE 1 --------------------------

PS C:\>join-path -path c:\win* -childpath System*

This command uses Join-Path to combine the "c:\Win*" path with the "System*" child path. The Windows PowerShell file system provider, FileSystem joins the path and adds the
"\" delimiter.

-------------------------- EXAMPLE 2 --------------------------

PS C:\>join-path c:\win* System* -resolve

This command displays the files and folders that are referenced by joining the "c:\Win*" path and the "System*" child path. It displays the same files and folders as
Get-ChildItem, but it displays the fully qualified path to each item. In this command, the Path and ChildPath optional parameter names are omitted.

-------------------------- EXAMPLE 3 --------------------------

PS C:\>PS HKLM:\> join-path System *ControlSet* -resolve

This command displays the registry keys in the HKLM\System registry subkey that include "ControlSet". This example shows how to use Join-Path with the Windows PowerShell
registry provider.

-------------------------- EXAMPLE 4 --------------------------

PS C:\>join-path -path C:, D:, E:, F: -childpath New

This command uses Join-Path to combine multiple path roots with a child path.

-------------------------- EXAMPLE 5 --------------------------

PS C:\>get-psdrive -psprovider filesystem | foreach {$_.root} | join-path -childpath Subdir

This command combines the roots of each Windows PowerShell file system drive in the console with the Subdir child path.

The command uses the Get-PSDrive cmdlet to get the Windows PowerShell drives supported by the FileSystem provider. The ForEach statement selects only the Root property of
the PSDriveInfo objects and combines it with the specified child path.

The output shows that the Windows PowerShell drives on the computer included a drive mapped to the C:\Program Files directory.
