Powershell dump in C with variable name

Good Morning,

I found a script to read out memberships of a User from active directory as per below.


[CmdletBinding(SupportsShouldProcess=$True)]
Param(
       [Parameter(Mandatory = $True)]
       [String]$UserName
)
Import-Module ActiveDirectory
If ($UserName) {
       $UserName = $UserName.ToUpper().Trim()
       $Res = (Get-ADPrincipalGroupMembership $UserName | Measure-Object).Count
       If ($Res -GT 0) {
              Write-Output "`n"
              Write-Output "The User $UserName Is A Member Of The Following Groups:"
              Write-Output "==========================================================="
              Get-ADPrincipalGroupMembership $UserName | Select-Object -Property Name, GroupScope, GroupCategory | Sort-Object -Property Name | FT -A
       }
}

This has been tested and worked fine.

Please guide me on how to Save the outcome in C$ +with the usename variable.txt and then step two copy the txt file from C:\ to remote share (xcopy).

All this has to be within the same powershelll command.

Thanks in advance.
