Since this is a learning-by-doing article, there are some prerequisites to ensure that you can follow the examples.

Below are the basic requirements. There are four methods to use PowerShell to download files that do not depend on third-party tools. These are:. Whichever one of these four methods you use, the logic and components to make them work are the same. If required by the webserver, you need to enter the credentials as well.

The next sections show each of these four methods. Whether the source location requires users to log in, the Invoke-WebRequest cmdlet can handle requests with credentials as well. To download a file, the syntax below shows the minimum parameters required to achieve the desired outcome.

For example, the code below downloads a file with the name 10MB. You may copy the code below and paste it into your PowerShell session to test.

The demonstration below shows the expected result after running the code above in PowerShell. As you can see, the file download was successful. How about if the source requires authentication before allowing access? For example, the code below downloads a file from a private website where users must log in. If authentication is required, you should add a credential to the request using the -Credential parameter.

As you can see, the Get-Credential cmdlet prompted a PowerShell credential request. Normally when you restart a download of the same filename, it will append a number starting with. If you want to schedule a large download ahead of time, it is worth checking that the remote files exist. The option to run a check on files is --spider.

In circumstances such as this, you will usually have a file with the list of files to download inside. An example of how this command will look when checking for a list of files is:. If you want to copy an entire website you will need to use the --mirror option.

As this can be a complicated task there are other options you may need to use such as -p , -P , --convert-links , --reject and --user-agent. It is always best to ask permission before downloading a site belonging to someone else and even if you have permission it is always good to play nice with their server.

If you want to download a file via FTP and a username and password is required, then you will need to use the --ftp-user and --ftp-password options.

The command also creates a log file in the working directory instead of printing output on the console. You may also put several options together, which do not require arguments. Below, you can see that instead of writing options separately -d -r -c , you can combine them in this format -drc. Rather than just a single web page, you may also want to download an entire website to see how the website is built. Wget downloads all the files that make up the entire website to the local-dir folder, as shown below.

The command below outputs the same result as the previous one you executed. The difference is that the --wait option sets a second interval in downloading each web page. While the --limit option sets the download speed limit to 50K mbps. As you did in the previous examples, downloading files manually each day is obviously a tedious task.

Wget offers the flexibility to download files from multiple URLs with a single command, requiring a single text file. Open your favorite text editor and put in the URLs of the files you wish to download, each on a new line, like the image below. By now, you already know your way of downloading files with the wget command. But perhaps, your download was interrupted during the download. What would you do?

Another great feature of wget is the flexibility to resume an interrupted or failed download. Below is an example of an interrupted download as you lost your internet connection. The download progress will automatically resume when you get your internet connection back.
