Modifying the Powershell calculated property with directory size - powershell

Question

I am trying to modify the below script to add one more column 'Directory size' so that it shows the total directory size for NTFS share.
Function Get-SmbSharePermission([String]$ComputerName = '.') {
$Shares = #{}
Get-WmiObject -Class Win32_Share -ComputerName $ComputerName | ForEach-Object {$Shares[$_.Name] = $_.Path}
Get-WmiObject -Class Win32_LogicalShareSecuritySetting -ComputerName $ComputerName | ForEach-Object {
$Name = $_.Name
$_.GetSecurityDescriptor().Descriptor.DACL | Select-Object -Property `
#{n='ComputerName'; e={$ComputerName}},
#{n='Name'; e={$Name}},
#{n='Path'; e={$Shares[$Name]}},
#{n='Account'; e={"$($_.Trustee.Domain)\$($_.Trustee.Name)".Trim('\')}},
#{n='Permission'; e={
Switch ($_.AccessMask) {
0x001F01FF {'Full'}
0x001301BF {'Change'}
0x001200A9 {'Read'}
default {"0x$($_.ToString('X8'))"}
}
}},
#{n='Type'; e={If ($_.AceType) {'Deny'} Else {'Allow'}}}
}
}
Get-SmbSharePermission | ogv
The script above does almost everything, except the total size of the directory.
How can I integrate it with the below function that can show the directory size?
$scriptBlock = {
param ([string]$Path,
[string]$GroupName)
# Get the total directory number and file counts
# the '/L' [for List] tells robocopy to not do anything, just list what it _would_ do
# /E :: copy subdirectories, including Empty ones.
# /L :: List only - don't copy, timestamp or delete any files.
# /NFL :: No File List - don't log file names.
# /NDL :: No Directory List - don't log directory names.
# /NP :: No Progress - don't display percentage copied.
$RC_Results = robocopy $Path 'NULL' /L /E /NP /NFL /NDL
# check to see if i forgot to re-enable the robocopy run [*blush*]
if ($RC_Results.Count -eq 0)
{
Write-Warning "You need to remove the `#` on line 2."
break
}
# the summary table is the first 5 of the last 7 lines
$RC_Summary = $RC_Results |
Select-Object -Last 7 |
Select-Object -First 5
# add a 'Type' column header to the 1st line
$RC_Summary[0] = 'Type' + $RC_Summary[0]
# add placeholders for the blank 'Times' [last line] columns
$RC_Summary[-1] = $RC_Summary[-1].
Insert(39, 'N/A').
Insert(49, 'N/A')
$NewRC_Summary = #()
# line cleanup
foreach ($Line in $RC_Summary)
{
# remove leading and trailing spaces
$NewLine = $Line.Trim()
# remove ':' that are NOT in time spans
$NewLine = $NewLine.Replace(' :', '')
# replace multi-spaces with singletons
$NewLine = $NewLine -replace '\s{2,}', ' '
# remove space between number and unit letter [bytes, kilobytes, etc.]
# 1.22 m >> 1.22m
$NewLine = $NewLine -replace '(\d)\s([bkmg])', '$1$2'
# replace remaining spaces with a comma
$NewLine = $NewLine.Replace(' ', ',')
# add to the new summary collection
$NewRC_Summary += $NewLine
}
$RC_SummaryTable = #{ }
foreach ($Item in ($NewRC_Summary | ConvertFrom-Csv))
{
$RC_SummaryTable.Add($Item.Type, $Item.Total)
}
[PSCustomObject] #{
DirPath = $Path
DirCount = "{0}" -f $RC_SummaryTable['Dirs']
FileCount = "{0}" -f $RC_SummaryTable['Files']
TotalSize = "{0}" -f $RC_SummaryTable['Bytes']
}
}
Update
The suggested code by Cpt. Whale below shows the whole disk drive size not each directories under Path:

I prefer to use volume information rather than doing a complete file listing via robocopy. I'm using the newer CimInstance powershell cmdlets here to get the volume information via Get-SmbShare:
Function Get-SmbSharePermission([String]$ComputerName = '.') {
# Create a cim session to use later, and get a list of the remote share objects:
$cim = New-CimSession -ComputerName $Computername
$shares = Get-SmbShare -CimSession $cim | Where Name -NotIn 'print$','IPC$'
# Iterate through each share
Foreach ($Share in $shares) {
# Skip shares without volume info (not file shares, e.g. shared printers)
if(!$Share.Volume){continue}
# Get the assoviated volume size
$Volume = Get-Volume -CimSession $cim -UniqueId $Share.Volume
# Get the access information, and format
Get-SmbShareAccess -CimSession $cim -Name $Share.Name | Select `
#{n='ComputerName'; e={$ComputerName}},
#{n='Name'; e={$Share.Name}},
#{n='Path'; e={$Share.Path}},
#{n='Account'; e={$_.AccountName}},
#{n='Permission'; e={$_.AccessRight}},
#{n='Type'; e={$_.AccessControlType}},
#{n='Drive'; e={$Volume.DriveLetter}},
#{n='TotalSize'; e={[String][Math]::Round($Volume.Size/1GB)+' GB'}},
#{n='FreeSpace'; e={[String][Math]::Round($Volume.SizeRemaining/1GB)+' GB'}}
}
}
# Output:
Get-SmbSharePermission | ft
ComputerName Name Path Account Permission Type Drive TotalSize FreeSpace
