How to Get FileName without Extension in PowerShell

To get the filename without the extension from a full file path in PowerShell, you can use the Split-Path command to extract the filename and then use the Split() method or System.IO.Path .NET class to remove the extension.

The following methods can be used to get a filename without extension in PowerShell.

Method 1: Using the Split-Path and Split() method

# specify the full file path
$filePath = "C:\temp\log\my_log.txt"

# Get the filename from the path
$fileName = Split-Path -Path $filePath -Leaf

# Remove the extension from the filename

$fileNameWithoutExtension = $fileName.Split(".")[0] 

# Write the filename without extension

Write-Output $fileNameWithoutExtension

This example will extract the filename from the full file path without extension using the Split-Path cmdlet and Split() method.

Method 2: Using the [System.IO.Path] .NET class

# specify the full file path
$filePath = "C:\temp\log\my_log.txt"

# Get the filename from the path
$fileName = Split-Path -Path $filePath -Leaf

# Remove the extension from the filename
$fileNameWithoutExtension = [System.IO.Path]::GetFileNameWithoutExtension($fileName)


# Write the filename without extension

Write-Output $fileNameWithoutExtension

This example will get the filename without an extension from a full file path using the .NET class.

The following examples show how to use these methods.

Get FileName without Extension Using Split-Path Cmdlet and Split() Method

You can use the Split-Path cmdlet to extract the filename from the full file path and then use the Split() method to get the filename without an extension.

# specify the full file path
$filePath = "C:\temp\log\my_log.txt"

# Get the filename from the path
$fileName = Split-Path -Path $filePath -Leaf

# Remove the extension from the filename

$fileNameWithoutExtension = $fileName.Split(".")[0] 

# Write the filename without extension

Write-Output $fileNameWithoutExtension

Output:

In this script, the $filePath variable stores the full file path. The Split-Path cmdlet uses the -Path and -Leaf parameters to extract the filename from the full file path and stores it in the $fileName variable.

Finally, it uses the Split() method over the $fileName variable to get the filename without an extension and output to the console using the Write-Output cmdlet.

After executing the script, it displays the file name without an extension “my_log” onto the console.

Get FileName without Extension Using System.IO.Path class

You can use the [System.IO.Path] .NET class to get the file name without an extension. It uses the GetFileNameWithoutExtension() method to extract the filename.

# specify the full file path
$filePath = "C:\temp\log\my_log.txt"

# Get the filename from the path
$fileName = Split-Path -Path $filePath -Leaf

# Remove the extension from the filename
$fileNameWithoutExtension = [System.IO.Path]::GetFileNameWithoutExtension($fileName)


# Write the filename without extension

Write-Output $fileNameWithoutExtension

Output:

In this script, the $filePath variable stores the full file path. The Split-Path command uses the -Path and -Leaf parameters to extract the filename from the full file path and store it in the $fileName variable.

Finally, it uses the GetFileNameWithoutExtension() method of the [System.IO.Path] class to get the filename and output to the console using the Write-Output command.

After executing the script, it displays the filename without an extension “my_log” onto the console.
