Copy a single file using Robocopy with long path

The script below is run from a shortcut in the "Send To" folder. By right-clicking a file and selecting the relevant menu item from the "Send to" menu, the file is copied to a special folder in Documents, then opened in it's default application. It works fine with paths up to 260 characters, but fails if a path exceeds that limit.

I tried to use Robocopy (refer to script), but apparently the long path issue is also affecting Split-Path so I can't get the source folder or file name.

Is there a solution? It doesn't have to use Robocopy. Copied files overwriting older files is okay.

#Get the source file path and name
param([string]$SourceFile)

#Shared folder workaround Part 1
#---------------------------------------------------------------------------------------------------
New-PSDrive -Name source -PSProvider FileSystem -Root \\machine1\abc\123 | Out-Null

New-PSDrive -Name target -PSProvider FileSystem -Root \\machine2\c$\Logs | Out-Null
#---------------------------------------------------------------------------------------------------

#Create the the destination folder string Part 1  - get the profile's Documents path
[string]$DestinationFolder = [Environment]::GetFolderPath("MyDocuments")

#Create the the destination folder string Part 2 - add the folder's name to which the file will be copied
$DestinationFolder = "$DestinationFolder\folder to receive the files\" 

#Create the destination folder if it does not exist
New-Item -ItemType Directory -Force -Path $DestinationFolder

#Copy the source file to the destination folder, quotes added to encapsulate spaces (this fails with long paths)
Copy-Item -Path "$SourceFile" -Destination $DestinationFolder

#Tried using Robocopy but apparently can't get the path or file name due to long file path issue
#Robocopy Split-Path -Path "$SourceFile"  $DestinationFolder Split-Path "$SourceFile" -Leaf

#Shared folder workaround Part 2
#---------------------------------------------------------------------------------------------------
Remove-PSDrive source

Remove-PSDrive target
#---------------------------------------------------------------------------------------------------

#Get the copied file name, quotes added to encapsulate spaces
[string]$NewFile = Split-Path  "$SourceFile" -Leaf

#Add the destination folder to the string
$NewFile = $DestinationFolder +  $NewFile

#Open the copied file
Invoke-Item -Path $NewFile

Edit

As far as I can tell, the very first line of code is the problem.

param([string]$SourceFile)

How can I edit this to work with long file names?

Wasif, in the comments below, has suggested I use \\?\ before $SourceFile. I have tried this as in "\\?\$SourceFile", but it does not work. I also tried editing the shortcut property in the SendTo folder. That did not work either.

You can prefix \\?\ to make windows API not follow the 260 char limit:

$DestinationFolder = "\\?\$($DestinationFolder)\folder to receive the files\"
