Get Folder Size from Windows Command Line

Question

Is it possible in Windows to get a folder s size from the command line without using any 3rd party tool   I want the same result as you would get when right clicking the folder in the windows explorer   properties

You can just add up sizes recursively  the following is a batch file    echo off set size 0 for  r   x in  folder    do set  a size     zx echo  size  Bytes  However  this has several problems because cmd is limited to 32-bit signed integer arithmetic  So it will get sizes above 2 GiB wrong1  Furthermore it will likely count symlinks and junctions multiple times so it s at best an upper bound  not the true size  you ll have that problem with any tool  though   An alternative is PowerShell  Get-ChildItem -Recurse   Measure-Object -Sum Length  or shorter  ls -r   measure -sum Length  If you want it prettier  switch  ls -r measure -sum Length  Sum          -gt 1GB          0 0 0  GiB  -f     1GB      break           -gt 1MB          0 0 0  MiB  -f     1MB      break           -gt 1KB          0 0 0  KiB  -f     1KB      break       default    quot    bytes quot       You can use this directly from cmd  powershell -noprofile -command  quot ls -r measure -sum Length quot    1 I do have a partially-finished bignum library in batch files somewhere which at least gets arbitrary-precision integer addition right  I should really release it  I guess  -

I guess this would only work if the directory is fairly static and its contents don t change between the execution of the two dir commands  Maybe a way to combine this into one command to avoid that  but this worked for my purpose  I didn t want the full listing  just the summary    GetDirSummary bat Script    echo off rem  get total number of lines from dir output FOR  F  delims     i IN   dir  S  1    find  asdfasdfasdf   C  V   DO set lineCount   i rem  dir summary is always last 3 lines  calculate starting line of summary info set  a summaryStart  lineCount-3  rem  now output just the last 3 lines dir  S  1   more   summaryStart    Usage   GetDirSummary bat c  temp  Output    Total Files Listed            22 File s          63 600 bytes            8 Dir s   104 350 330 880 bytes free

Try   SET FOLDERSIZE 0 FOR  F  tokens 3   A IN   DIR  C  Program Files   a  -c  s    FINDSTR  C   bytes     FINDSTR  V  C   bytes free    DO SET FOLDERSIZE  A   Change C  Program Files to whatever folder you want and change  A to   A if using in a batch file  It returns the size of the whole folder  including subfolders and hidden and system files  and works with folders over 2GB  It does write to the screen  so you ll have to use an interim file if you don t want that

I think your only option will be diruse  a highly supported 3rd party solution    Get file directory size from command line  The Windows CLI is unfortuntely quite restrictive  you could alternatively install Cygwin which is a dream to use compared to cmd  That would give you access to the ported Unix tool du which is the basis of diruse on windows   Sorry I wasn t able to answer your questions directly with a command you can run on the native cli
