Hello,

The difference between the -Path and -LiteralPath, -Name and -LiteralName parameters lies in whether or not wildcards (*?[]) are supported.

Let’s check this with a few commands

# Test the following commands:
get-item -LiteralPath C:\Windows\System
get-item -Path C:\Windows\System
# There is no difference

# Test the following commands:
get-item -LiteralPath C:\Windows\System??
get-item -Path C:\Windows\System??
-LiteralPath does not work with wildcards

# You can check this by looking at the help
Get-Help Get-Item
"-LiteralPath <System.String[]>"
"..."
"Accept wildcards? false"

"-Path <System.String[]>"
"..."
"Accept wildcards?  True"

# Let's do a test by creating 2 folders
mkdir c:\book
mkdir c:\look

# Use wildcards to find the 2 folders
Get-Item -Path c:\[bl]ook
# Both folders are displayed
Get-Item -LiteralPath c:\[bl]ook
# Aucun résultat

# Another test (characters [] are allowed in folder and file names)
mkdir c:\[bl]ook
Get-Item -LiteralPath c:\[bl]ook
# The folder is displayed
