Last Modified: 2014-11-27
Hi
 I am trying to get folder sizes of shared  folders that are located on network drives. However when l use the Powershell script attached. I only get the first  3 folder sizes within each shared folder that l run the script on. I would like  the script to include all the folders in the shared  folder. I would appreciate your assistance.
$a = Get-Date
$Year = $a.Year
$Month = $a.Month
$Day = $a.Day
$report = "c:\Scripts\Folder Size $Year$Month$Day.txt"

"Date: " + $a.ToShortDateString()  | Out-File -FilePath $report
"Time: " + $a.ToShortTimeString()  | Out-File -Append -FilePath $report


Out-File -Append -FilePath $report -InputObject "----------------------------------------------------------------" 
Out-File -Append -FilePath $report -InputObject "---                 Start of Script                          ---" 
Out-File -Append -FilePath $report -InputObject "----------------------------------------------------------------" 

Function RootScan
  {
  #List all root folders in the drive
  $folders = Get-ChildItem -Path $mainfolder | ? { $_.psiscontainer -and $_.FullName -notmatch $exclude}
  #$folders = Get-ChildItem -Path $mainfolder -exclude $exclude | ? { $_.psiscontainer -and $_.FullName}
  Out-File -Append -FilePath $report -InputObject "Start Root"
  ForEach ($folder in $folders)
  {
    $subFolderItems = (Get-ChildItem $folder.FullName -Recurse | Measure-Object -property length -sum)
    $folder.FullName + " -- " + "{0:N2}" -f ($subFolderItems.sum / 1MB) + " MB" | Out-File -Append -FilePath $report
  }
Out-File -Append -FilePath $report -InputObject "Finished Root"
}

Function SubScan
{
#List all Group folders in the GroupDrive
ForEach ($folderGroup in $Group)
{
  #Write-Host "This is FolderGroup: $folderGroup"
  $foldersGroup = Get-ChildItem -Path $foldergroup | ? { $_.psiscontainer -and $_.FullName}
  $SubNum = $SubNum + 1
  Out-File -Append -FilePath $report -InputObject "Start $SubNum"

    ForEach ($child in $foldersGroup)
    {
    #Write-Host "This is FoldersGroup: $child"
    $subFolderItems = (Get-ChildItem $child.FullName -Recurse | Measure-Object -property length -sum)
    $Child.FullName + " -- " + "{0:N2}" -f ($subFolderItems.sum / 1MB) + " MB" | Out-File -Append -FilePath $report
    }
  
  Out-File -Append -FilePath $report -InputObject "Finished $SubNum"
}}

$mainfolder = "M:\small"
$SubNum = 2
#Enter Directories Requiring Individual Subfolder Count
#$Group = "C:\Temp\"
#Enter Directories Excluded from Root Count
$exclude = "Users Data", "Test"
RootScan
#SubScan

#$mainfolder = "c:\Temp"
#$SubNum = 1
#Enter Directories Requiring Individual Subfolder Count
#$Group = "c:\Temp"
#Enter Directories Excluded from Root Count
#$exclude = "1"
#RootScan
#SubScan

Out-File -Append -FilePath $report -InputObject  "----------------------------------------------------------------"
Out-File -Append -FilePath $report -InputObject  "---                 End of Script                            ---"
Out-File -Append -FilePath $report -InputObject  "----------------------------------------------------------------"

$a = Get-Date
"Date: " + $a.ToShortDateString()  | Out-File -Append -FilePath $report

All the permissons are similar on all the drives  and folders but the result is the same when l run the script on any of them l can only get the results for the first 3 folders. So doubt that can be the issue, however the drives are SAN drives  mapped to the server via ICSI and the permisson are inherited from the root folder

Hi Qlemo
 You could be right, I  have seen the results of one of the drives on the server  and it has listed all the folders for the root folder so that  means the sctipt is working, so l will re-examine the permissons on the drives that have failed.

Hi Qlemo
I have changed the permissions and it has worked, thanks. However l have a new question, l can understand if it is not possible to answer it and l will be happy to close the question. Is it possible to have the script run and scan 3 folders are the same time or am l asking for too much?

Though, it would be much better to generate objects instead of strings, and export as CSV ...
