Get the total size of all subdirectories with a specific name

#1 Post by terryhenderson » 28 Sep 2020 04:03

I have a long and deep tree which contains numerous subdirectories for many levels down.
"resfiles" is one of those subdirectories that exists in various levels of that tree.
What I need is a cmd or a batch that sums the total size of all resfiles subdirectories in all levels and returns:
1. the number of resfiles subdirectories
2. the total size of all those resfiles subdirectories of that tree.


Can I get some precious assistance with this issue, please?

Many thanks in advance.

There are some threads about the size of a directory here at DosTips, like that one:
viewtopic.php?f=3&t=9615&p=62024

Although I still have my doubts that Batch is the right language for a task like this. Even if you are able to get the total size, keep in mind that math in Batch is limited to 32 bit integers.

Thank you very much indeed Steffen for your reply.
I believe the referred to link does have the solution for my question. I just need to specifically refer to any "resfiles" subfolder in this code:

Code: Select all

@echo off &setlocal
set "folder=%userprofile%\Desktop"
for /f "tokens=1,2 delims=: " %%a in ('robocopy "%folder%" "%folder%" /L /S /NJH /BYTES /FP /NC /NDL /NFL /TS /XJ /R:0 /W:0') do if /i "%%a"=="Bytes" set "size=%%b"
echo %size% bytes
pause
how this can be done in:

Code: Select all

set "folder=%userprofile%\Desktop"
I really appreciate any advice.

Many thanks ..

Basically not a big deal

Code: Select all

@echo off &setlocal
set "root=C:\somewhwere"
set "folder=resfiles"

set /a "count=0,size=0"
for /f "delims=" %%i in ('dir /ad /b /s "%root%\*%folder%"^|findstr /eic:"\\%folder%"') do (
  set /a "count+=1"
  for /f "tokens=1,2 delims=: " %%a in ('robocopy "%%i" "%%i" /L /S /NJH /BYTES /FP /NC /NDL /NFL /TS /XJ /R:0 /W:0') do if /i "%%a"=="Bytes" set /a "size+=%%b"
)

echo %count%
echo %size%
pause
But now you have the SET /A statement to summerize the the sizes of the found directories. I can't see on your desktop and thus, I have no idea if the 32 bit limit I've been talking about might be problematic in your case. However, anything above 2147483647 isn't recognized as a numeric value anymore. In case of the size this means 2GB is already one byte too much.
