This will display the size (in MegaBytes) of your archive and number of files. If you use the ‘-Export’ switch, it will export a list of files to each directory. You can use Robocopy as an alternative to Get-ChildItem for better performance.

function Get-ArchiveSize {
    [CmdletBinding()]
    Param(
        [Parameter(ValueFromPipeline)]
        [string[]]$Path,
        [switch]$Export
    )

Process {
    foreach ($string in $path){
    Write-Verbose "Searching [$string]"
    $files = Get-ChildItem -Path $string -File -Attributes Archive -Recurse
    $measure = $files | Measure-Object -Sum Length | 
    Select-Object @{n='Sum';exp={"{0:N2} (MB)" -f ($_.Sum / 1MB)}},
    Count | Format-Table -AutoSize
    $measure
    If ($Export){$files.FullName | Out-File "$string\filelist.txt" -Append}
    }
} 
}

# Examples:
# Get-ArchiveSize -Path "\\path\one","\\path\two" -Verbose
#  "\\path\one","\\path\two" | Get-ArchiveSize -Verbose -Export
