Powershell folder size of folders without listing Subdirectories

Question

I have found several resources that use the following script to get folder sizes   colItems    Get-ChildItem  startFolder -recurse   Where-Object     PSIsContainer -eq  True    Sort-Object  foreach   i in  colItems                 subFolderItems    Get-ChildItem  i FullName   Measure-Object -property length -sum           i FullName     --       0 N2   -f   subFolderItems sum   1MB      MB          The problem with that is it also lists the subdirectories ie   c  test 1 -- 10mb c  test 1 folder -- 10mb c  test 1 folder deep -- 5mb c  test 1 folder tuna -- 5mb c  test 2 -- 20bm c  test 2 folder -- 20mb c  test 2 folder deep -- 10mb c  test 2 folder tuna -- 10mb   I think you know see where I am going   What I am looking for is just the parent folder s results     SO   c  test 1 -- 10mb c  test 2 -- 20mb   How can this be accomplished with Powershell

This is similar to https   stackoverflow com users 3396598 kohlbrr answer  but I was trying to get the total size of a single folder and found that the script doesn t count the files in the Root of the folder you are searching  This worked for me    startFolder    C  Users    totalSize   0    colItems   Get-ChildItem  startFolder foreach   i in  colItems         subFolderItems   Get-ChildItem  i FullName -recurse -force   Where-Object     PSIsContainer -eq  false    Measure-Object -property Length -sum   Select-Object Sum      totalSize    totalSize    subFolderItems sum   1MB      startFolder             0 N2   -f   totalSize      MB

You need to get the total contents size of each directory recursively to output  Also  you need to specify that the contents you re grabbing to measure are not directories  or you risk errors  as directories do not have a Length parameter    Here s your script modified for the output you re looking for    colItems   Get-ChildItem  startFolder   Where-Object     PSIsContainer -eq  true    Sort-Object foreach   i in  colItems         subFolderItems   Get-ChildItem  i FullName -recurse -force   Where-Object     PSIsContainer -eq  false    Measure-Object -property Length -sum   Select-Object Sum      i FullName     --       0 N2   -f   subFolderItems sum   1MB      MB

At the answer from  squicc if you amend this line   topDir   Get-ChildItem -directory  C  test  with -force then you will be able to see the hidden directories also  Without this  the size will be different when you run the solution from inside or outside the folder

Sorry to reanimate a dead thread  but I have just been dealing with this myself  and after finding all sorts of crazy bloated solutions  I managed to come up with this    Long  actualSize   0 foreach   item in  Get-ChildItem  path -recurse   Where  -not    PSIsContainer    ForEach-Object     FullName          actualSize     Get-Item  item  length     Quickly and in few lines of code gives me a folder size in Bytes  than can easily be converted to any units you want with   1MB or the like  Am I missing something  Compared to this overwrought mess it seems rather simple and to the point  Not to mention that code doesn t even work since the called function is not the same name as the defined function  And has been wrong for 6 years     So  any reasons NOT to use this stripped down approach

The solution posted by  Linga   quot Get-ChildItem -Recurse  directory path    Measure-Object -Property Length -Sum quot  is nice and short  However  it only computes the size of  directory path   without sub-directories  Here is a simple solution for listing all sub-directory sizes  With a little pretty-printing added   Note  use the -File option to avoid errors for empty sub-directories  foreach   d in gci -Directory -Force        0 N0   -f   gci  d -File -Recurse -Force   measure length -sum  sum     quot  t t d quot

Interesting how powerful yet how helpless PS can be in the same time  coming from a Nix learning PS  after install crgwin gitbash  you can do any combination in one commands   size of current folder  du -sk     size of all files and folders under current directory du -sk    size of all subfolders  including current folders  find    -type d -exec du -sk

from sysinternals com with du exe or du64 exe -l 1   or 2 levels down    du -l 2 c     Much shorter than Linux though

This simple solution worked for me as well   powershell -c  Get-ChildItem -Recurse  directory path    Measure-Object -Property Length -Sum

This is something I wind up looking for repeatedly  even though I wrote myself a nice little function a while ago   So  I figured others might benefit from having it and maybe I ll even find it here  myself   hahaha  It s pretty simple to paste into your script and use   Just pass it a folder object     I think it requires PowerShell 3 just because of the -directory flag on the Get-ChildItem command  but I m sure it can be easily adapted  if need be     function Get-TreeSize   folder    null         Function to get recursive folder size      result            folderResult        Select-Object FolderPath  FolderName  SizeKB  SizeMB  SizeGB  OverThreshold       contents    Get-ChildItem  folder FullName -recurse -force -erroraction SilentlyContinue -Include     Where-Object     psiscontainer -eq  false    Measure-Object -Property length -sum   Select-Object sum      sizeKB    math   Round  contents sum   1000 3      ToString              sizeMB    math   Round  contents sum   1000000 3      ToString              sizeGB    math   Round  contents sum   1000000000 3      ToString                folderResult FolderPath    folder FullName      folderResult FolderName    folder BaseName      folderResult SizeKB    sizeKB      folderresult SizeMB    sizeMB      folderresult SizeGB    sizeGB      result     folderResult      return  result       Use the function like this for a single directory  topDir   get-item  C  test  Get-TreeSize   topDir    Use the function like this for all top level folders within a direcotry   topDir   gci -directory    server share folder   topDir   Get-ChildItem -directory  C  test  foreach   folderPath in  topDir   Get-TreeSize  folderPath
