Start-BitsTransfer is designed specifically for transferring files between client and server computers. Some of these benefits are:. The fundamental way to use Start-BitsTransfer in PowerShell to download a file is to specify a source and destination. Suppose the destination is not specified, Start-BitsTransfer downloads and saves the file to the current working directory.
Name the file filelist. The first column should contain the link to the source, while the second column must contain the destination path. The file contents would like the one below.
Once the CSV file is ready, use the command below to begin the file download. Refer to the demo below to see how the code above works. As you can see, the download starts, and you see the download progress. The PowerShell prompt is not available during the download process. Suppose you want to start the download process as a background job. To do so, you only have to add the -Asynchronous switch at the end of the Start-BitsTransfer command. Initially, the state of each job would show c onnecting.
To check the download job status, use the Get-BitsTransfer cmdlet. PowerShell is based on. NET, and its nature makes it capable of leveraging the power of. NET itself. If you want to know more about these two. HttpClient vs. To use the WebClient class, you need to initiate an object as a System. WebClient object. Then, using the DownloadFile method starts the download of the file from the source. Please copy the code below and run it in your PowerShell session to test.
However, the PowerShell prompt will be locked until the download is complete. If the source requires authentication to allow the file download, you can use the code below.
Instead, use the System. HttpClient class. It appears that the WebClient class is obsolete, and the new class that Microsoft is endorsing is the HttpClient class.

One more question to add to this. Is there a way to add a progress indicator? These are fairly large files and I don't want someone to think that the program died.
When you run each download as a separate Job , you run them in a different Runspace s and will have to do some work to get it to show progress. I suppose you could write progress information to output in the jobs and have the script which started the jobs read from the output streams continously and updating a progress bar. Perhaps there are simpler ways? How to do it, however, is a completely separate question, so I suggest you write a new question regarding that, if you run into problems in your own attempts at it.
You can possibly use write-Progress to do this. See: blogs. If you periodically Write-Output the current state in the Job the script which started the Job should be able to read this output and turn that into Write-Progress.
