Check if a file or folder exists with Test-Path

The PowerShell true/false existence test every script should start with — supports files, folders, registry keys, and wildcards.

Run Test-Path '<path>' — it returns True if the item exists, False if not; use in if (Test-Path ...) guards.

01Command

Command
$ Test-Path 'C:\Program Files\Git\bin\git.exe'

02What it does

Test-Path works on any PowerShell provider path: filesystem, registry (HKLM:\...), even environment variables. -PathType Leaf restricts the check to files and -PathType Container to folders, so you don't mistake a directory for the file you want. -IsValid checks only whether the path string is syntactically valid without touching the disk.

!Warning: Test-Path returns False for a path you can see but lack permission to probe on some network shares — don't treat False as a guarantee the item is gone.
