New-PSDrive creates a PowerShell drive that is "mapped" to a location in a data store, such as a network drive, a directory on the local computer, or a registry key.

Windows PowerShell drives are known only to PowerShell. They cannot be accessed by Windows Explorer, WMI or CMD tools.

Examples

Install a drive called 'SS64' using the file system provider. The drive will be rooted at "C:\MyDocs":

PS C:\> new-Psdrive -name SS64 -psProvider FileSystem -root C:\MyDocs
DIR SS64:

Install a drive called 'S:' using the file system provider. The drive will be rooted at \\Server64\workgroups:

PS C:\> new-Psdrive -name S -PsProvider FileSystem -root \\Server64\workgroups
S:
PS S:\> DIR S:

The parameters are positional, so
PS C:\> New-PSDrive -name M -psprovider FileSystem -root \\Server\Share

is the same as
PS C:\> New-PSDrive M FileSystem \\Server\Share

Map a drive using VBScript, calling .MapNetworkDrive from a Wscript.Network COM object, this method will make a persistent drive map:

PS C:\> $drive = new-object -com wscript.network
PS C:\> $drive.MapNetworkDrive("S:", "\\Server64\workgroups")
