$cs.File_GetFolderSize

Description

Calculates the total size, in bytes, of every file under path, including all subfolders. Throws DirectoryNotFoundException if path doesn’t exist.

Syntax

$cs.File_GetFolderSize(string path)

Parameters

path (String)

Full path of the folder to measure.

Return value

Long, the total size of the folder contents in bytes.

Example

PowerShell

$logFolder = $global:AppLogFolder
if ($cs.File_ExistDir($logFolder))
{
  $sizeInBytes = $cs.File_GetFolderSize($logFolder)
  $cs.Job_WriteLog("Log folder size: $sizeInBytes bytes")
}

Sanity-check that an extraction step actually produced files, rather than silently leaving an empty folder:

$extractFolder = Join-Path $global:Packageroot "Extracted"
if ($cs.File_ExistDir($extractFolder))
{
  $sizeInBytes = $cs.File_GetFolderSize($extractFolder)
  if ($sizeInBytes -eq 0)
  {
    Exit-PSScript -exitcode 1 -exitmessage "Extraction produced an empty folder, aborting install"
  }
}

Log how much space a data folder is using before removing it during cleanup:

$dataFolder = Join-Path $env:ProgramData "Contoso\Cache"
if ($cs.File_ExistDir($dataFolder))
{
  $sizeInMb = [math]::Round($cs.File_GetFolderSize($dataFolder) / 1MB, 2)
  $cs.Job_WriteLog("Removing cache folder ($sizeInMb MB) at $dataFolder")
  $cs.File_DelTree($dataFolder)
}

$cs.File_ExistDir $cs.File_DelTree
