How to Set File Name to Default When Downloaded With Powershell?

2 minutes read

In PowerShell, you can set the file name to default when downloading a file by using the Invoke-WebRequest cmdlet. By specifying the -OutFile parameter followed by the desired file path, you can set the file name to be the same as the default name that the file has on the server. This way, the downloaded file will have its original name and extension. Additionally, you can also use the -UseBasicParsing parameter to avoid potential issues with parsing HTML content when downloading files in PowerShell.


What is the default file name in PowerShell downloads?

The default file name in PowerShell downloads is typically the same as the original file name of the file being downloaded. However, you can specify a different file name using the -OutFile parameter in the Invoke-WebRequest cmdlet.


What is the command to set the default file name in PowerShell?

In PowerShell, you can set the default file name using the $PSDefaultParameterValues variable.


For example, to set the default file name for the Out-File cmdlet, you can use the following command:

1
2
3

$PSDefaultParameterValues = @{
    'Out-File:FilePath' = 'C:\defaultfilename.txt'
}


This command sets the default file name to C:\defaultfilename.txt when using the Out-File cmdlet. You can replace Out-File with any other cmdlet that accepts a file path parameter to set a default file name for that cmdlet.


What steps should I follow to ensure the default file name is used in PowerShell downloads?

To ensure that the default file name is used in PowerShell downloads, follow these steps:

  1. Specify the file name: When using the Invoke-WebRequest or Start-BitsTransfer cmdlets to download files in PowerShell, be sure to specify the desired file name in the -OutFile parameter. For example, if you want to download a file named example.pdf, use -OutFile example.pdf.
  2. Check for existing file: Before downloading the file, check if a file with the same name already exists in the download location. If it does, either rename or delete the existing file to avoid conflicts.
  3. Use full file path: Provide the full path of the file in the -OutFile parameter to ensure that the file is downloaded to the correct location. For example, -OutFile C:\Users\Username\Downloads\example.pdf.
  4. Confirm file extension: Be sure to include the correct file extension in the file name to ensure that the file is saved with the correct format. For example, if downloading a PDF file, make sure to include the ".pdf" extension in the file name.
  5. Handle errors: Check for any errors or warnings that may occur during the download process and handle them accordingly. This can help prevent issues with the download and ensure that the file is saved correctly.


By following these steps, you can ensure that the default file name is used in PowerShell downloads and that the files are saved correctly to the desired location.
