Sort by folder size

Question

Hello every one! I have this script:
$log = ".\logfile.log"
$startFolder = "C:\VMs"
$colItems = Get-ChildItem $startFolder | Where-Object {$_.PSIsContainer -eq $True} | Sort-Object
foreach ($i in $colItems){
$itemSum = Get-ChildItem ("$startFolder\" + $i.Name) -recurse | Measure-Object -property length -sum
"$startFolder\$i -- " + "{0:N2}" -f ($itemSum.sum / 1KB) + " KB" >> $log
import-csv $log -delimiter "`t" | export-csv .\TEST.csv
$body = Get-Content $log | Sort | Out-String
Send-MailMessage -From [email protected] -To [email protected] -Subject "Test Theme" -attachment .\TEST.csv -Encoding ([System.Text.Encoding]::UTF8) -Body $body -SmtpServer test123.test.local
Remove-Item $log
Remove-Item .\TEST.csv
When this script done I
receive something like this in email message:
C:\VMs\Backup -- 0,00 KB
C:\VMs\Vbox -- 82 874 750,42 KB
C:\VMs\VMWARE_BACKUP -- 182 818,77 KB
How I can change this script to sort by folder size?
Not alphabetically.
Thanks in advance!

Hello Darkwind,
you can do this, but it'll require some reformatting your script. I've done the honors:
$startFolder = "C:\VMs"
# Get folders
$colItems = Get-ChildItem $startFolder | Where-Object {$_.PSIsContainer -eq $True} | Sort-Object
# This one will do the measuring for us
$fso = New-Object -ComObject Scripting.FileSystemObject
# iterate over each folder and measure length
$FolderReport = @()
foreach ($i in $colItems)
# 1: Get Size
$folder = $fso.GetFolder($i.FullName)
$size = $folder.size
# 2: Set Properties in a hashtable
$props = @{
name = $i.FullName
size = $size
displaysize = (("{0:N2}" -f ($size / 1KB)) + " KB")
# 3: Add to results
$FolderReport += New-Object PSObject -Property $props
# Sort results
$FolderReport = $FolderReport | Sort size
# Build CSV attachment
$FolderReport | export-csv .\TEST.csv
# Build body
$lines = @()
$FolderReport | %{$lines += ($_.name + " -- " + $_.displaysize)}
$body = $lines -join "`n"
# Send mail
Send-MailMessage -From [email protected] -To [email protected] -Subject "Test Theme" -attachment .\TEST.csv -Encoding ([System.Text.Encoding]::UTF8) -Body $body -SmtpServer test123.test.local
# Cleanup file
Remove-Item .\TEST.csv
As you can see, some slight modifications :)
Now, just what did I change ...
I used the Scripting.FileSystemObject Comobject to measure size, since that's a bit faster.
When selecting the size, I built custom objects containing the information (Name & size), since if we want to sort by size, we need to keep it as a separate property.
Then I sorted by size, and exported the result into a csv file for attachment
I built the body from strings in memory - no point writing it to a file, just to reread it. (that "`n" should work as a linebreak)
Cheers,
Fred
There's no place like 127.0.0.1
Thank You! It's work for me!
But this script first shows the
folders from the small to the larger
size. Is it possible to do the opposite?
