How to get a selected file to break down to path and file for robocopy transfer?

Question

I am writing a script that opens a file explorer window for any user to select a file to then copy to a preselected machine into a temp folder. I want to be able to select a file anywhere on the machine and break down the path to the file and the file itself for robocopy to then copy it to \WIN10\C$\TEMP however I cannot seem to get it to break down properly.

function Copy-FileToMachines {
    Add-Type -AssemblyName System.Windows.Forms
    $fileBrowser = New-Object System.Windows.Forms.OpenFileDialog -Property @{
        InitialDirectory = [Environment]::GetFolderPath('Desktop')
    }

    $result = $fileBrowser.ShowDialog()

    if ($result -eq 'OK') {
        $file = $fileBrowser.SafeFileName
        $source = $fileBrowser.InitialDirectory

        $deviceList = @('Computer1', 'Computer2', 'Computer3')  # Add the names of destination computers here

        foreach ($device in $deviceList) {
            try {
                robocopy "$source" "\\$device\c$\Temp" "$file" /Z /NP /R:3 /W:5 /BYTES /LOG+:`"$env:TEMP\robocopy.log`" | Out-Null
                Write-Host "File successfully copied to $device"
            }
            catch {
                Write-Host "An error occurred while copying the file to $device: $_"
            }
        }
  }

The above lets me select a file in D:\SOFTWARE but when I read the .log file it shows the source as C:\USERS\ADMINISTRATORS\DESKTOP\

I understand that to be because of InitialDirectory, however I have changed it to Split-Path

$file = Split-Path $(FileBrowser.Filename) -Leaf
$source = Split-Path $(FileBrowser.File) -Parent

Now when I run it the .log shows the destination of \\WIN10\C$\TEMP as the source now and the file is now showing as *.* in the log.

What am I missing?

Use $fileBrowser.FileName in Split-Path. Remove the COLON character after $device.

function Copy-FileToMachines {
    Add-Type -AssemblyName System.Windows.Forms
    $fileBrowser = New-Object System.Windows.Forms.OpenFileDialog -Property @{
        InitialDirectory = [Environment]::GetFolderPath('Desktop')
    }

    $result = $fileBrowser.ShowDialog()

    if ($result -eq 'OK') {
        $file = $fileBrowser.SafeFileName
        $source = Split-Path -Path $fileBrowser.FileName -Parent     # InitialDirectory

        $deviceList = @('Computer1', 'Computer2', 'Computer3')  # Add the names of destination computers here

        foreach ($device in $deviceList) {
            try {
                robocopy "$source" "\\$device\c$\Temp" "$file" /Z /NP /R:3 /W:5 /BYTES /LOG+:`"$env:TEMP\robocopy.log`" | Out-Null
                Write-Host "File successfully copied to $device"
            }
            catch {
                Write-Host "An error occurred while copying the file to $device $_"
            }
        }
    }
}
