How to Check if a File Exists in Windows PowerShell

Sometimes, you get an error message saying the file does not exist in PowerShell.

This tutorial will introduce four methods to check if a file exists in PowerShell.

Use Test-Path to Check if a File Exists in PowerShell

The first method is the Test-Path cmdlet. It determines whether the complete path exists. It returns $True if the path exists and $False if any element is missing. The -PathType Leaf parameter checks for a file and not a directory.

Test-Path -Path "C:/New/test.txt" -PathType Leaf

Output:

True

If there is no file named file.txt in the directory New, it returns $False.

Test-Path -Path "C:/New/file.txt" -PathType Leaf

Output:

False

Use [System.IO.File]::Exists() to Check if a File Exists in PowerShell

Another method to check if a file exists is [System.IO.File]::Exists(). It provides a Boolean result, True if the file exists or False if the file does not exist.

[System.IO.File]::Exists("C:/New/test.txt")

Output:

True

Use Get-Item to Check if a File Exists in PowerShell

The Get-Item cmdlet is used to get the item at the specified path. You can use it to check if a file exists by specifying the file’s path. It prints the mode (attributes), last write time, length, and name of a file if it exists. It displays an error message if a file does not exist.

Get-Item C:/New/test.txt

Output:

Directory: C:\New

Mode                 LastWriteTime         Length Name
----                 -------------         ------ ----
-a----        12/11/2021   2:59 PM              5 test.txt

Below is the output when the file doesn’t exist.

Get-Item : Cannot find path 'C:\New\test10.txt' because it does not exist.
At line:1 char:1
+ Get-Item C:/test/test10.txt
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (C:\New\test10.txt:String) [Get-Item], ItemNotFoundException
    + FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.GetItemCommand

Use Get-ChildItem to Check if a File Exists in PowerShell

The last method is to use Get-ChildItem cmdlet. It gets the items and child items in one or more specified paths. It displays the file details if the file exists in the specified path.

Get-ChildItem -Path C:/New/test.txt

Output:

Directory: C:\New

Mode                 LastWriteTime         Length Name
----                 -------------         ------ ----
-a----        12/11/2021   2:59 PM              5 test.txt

It prints an error message saying Cannot find path '$path' because it does not exist. when a file is not found.

Get-ChildItem -Path C:/New/test

Output:

Get-ChildItem : Cannot find path 'C:\New\test' because it does not exist.
At line:1 char:1
+ Get-ChildItem -Path C:/New/test
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (C:\New\test:String) [Get-ChildItem], ItemNotFoundException
    + FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.GetChildItemCommand
