If you'd like to copy a file called file1.txt inside of C:\Folder to a remote computer SERVER1 on its C:\, you could do this: Copy-Item –Path C:\Folder1\file1.txt –Destination '\\SERVER1\c$' When you're using PowerShell Copy-Item via the traditional SMB method, you need to specify the Path and Destination parameters.
By using Copy-Item –ToSession, an administrator can ensure files will always be copied to a remote computer regardless of whether or not SMB is blocked. These standard ports are typically open to manage remote nodes, sometimes even to a DMZ environment. This process has a few different advantages, but included in the biggest benefits are the TCP ports used: 5985 (HTTP) and 5986 (HTTPS). It provides a way to transfer files over the same link that you might use today to execute commands remotely on computers with cmdlets like Invoke-Command.

This parameter was introduced with Windows Management Framework (WMF) v5 with the Copy-Item cmdlet. If you're in a high-security environment or need to transfer files from an internal network to a DMZ that might have various port restrictions, how can you ensure that your scripts are able to copy files to nodes all the time? One way to do so is to use PowerShell v5's Copy-Item cmdlet with the new –ToSession parameter. This is a common port that's usually open internally, except in some high-security situations or across a DMZ.
In the case of an SMB file copy, that port is 445. For a file copy process to get a file from point A to point B, a port needs to be open all the way to the destination node. Whether or not you think about this, all TCP network communication (such as SMB file copies) use network ports to make the bits transfer. Unfortunately, many administrators don't think about how this process occurs until it doesn't work. Once you specify the source and destination location, it just happens. It's easy to copy files with PowerShell Copy-Item via the command line.
