Hi guys just wondering if u can help me modify this script that ive been playing around with, i cant get it to accept wildcard charcters '*'
@echo off
setLocal EnableDelayedExpansion
set /a value=0
set /a sum=0
FOR /R %1 %%I IN (*) DO (
set /a value=%%~zI/1024
set /a sum=!sum!+!value!
)
@echo Size is: !sum! k
Its in a batch file called dirsize and is called like so
dirsize c:\folder
I want it to check folder sizes for me, this one here is an example, the cache in firefox
dirsize C:\users\%username%\AppData\Local\Mozilla\Firefox\*.default\Cache
Returns the value 0
But if I go
dirsize C:\users\%username%\AppData\Local\Mozilla\Firefox\sr1znnb4.default\Cache
It works and I get the value 55322 returned.. Help me please? Thank you in advance kind people
PowerShell makes this easy, of course:
(gci . -Recurse | Measure-Object -Property Length -Sum).Sum
And PowerShell is already installed on Windows 7. Get on the bandwagon! :-)
Also, C:\users\%USERNAME%\AppData\ isn't a reliable way of finding AppData. Try %APPDATA% (or $env:APPDATA in PowerShell).
Ok for a starter, lets say wildcards are not well supported throughout batch files, and specially in for loops.
That's what I came up with:
DirSize.cmd "valid path"
@echo off
rem Args[1]= "Path" or "valid path with wildcard"
set _size=0
set dRaw=%~1
echo %~1|findstr "*"&& set dSource=%~dp1|| (
set dSource=%~1\
if not "%dRaw:~-1%"=="\" set dRaw=%dRaw%\
)
for /f "delims=" %%D in ('dir /ad /b %dRaw%') do call :DirSize "%dSource%%%~D"
set /a size=_size/1024
echo size=%size% k (%_size% bytes)
exit /b 0
:DirSize
call :FileSize "%~1"
for /f "delims=" %%d in ('dir /ad /b "%~1"2^>nul') do call :DirSize "%~1\%%~d"
exit /b 0
:FileSize
for /f "delims=" %%f in ('dir /a-d /b "%~1\"2^>nul') do for %%F in (%1\%%f) do set /a _size+=%%~zF
exit /b 0
___Usage___
Argument: Needs to be a path (not a file) that either contain wildcards or not. Path need top be valid when typing dir path
___Notes___
This script does check for all files and sub-directories, even hidden/system ones.
change the dir /a argument and add -h-s (like /ad-h-s) to remove this behaviour.
I revised the argument checking to my liking now, so I think it is usable.
I hope this helps.
You would need to wrap what you currently have in another for loop which expands the * into a series of directories.
So
@echo off
setLocal EnableDelayedExpansion
set /a sum=0
for /d %%D in (%1) do (
FOR /R %%D %%I IN (*) DO (
set /a value=%%~zI/1024
set /a sum=!sum!+!value!
)
)
echo Size is: !sum! k
might work (untested, though, but should give you the general idea)
If you have a Windows version of grep (you can find one at GNU utilities for Win32) you can do something like this:
dir /s %1 | grep --after-context=1 "Total Files Listed:"
This code will increase directory size limit up to 2,000,000 TB and will display more real size, what would be useful if the folder contains too many files.
rem SET DIR=%1
SET DIR=C:\DIR1\
IF NOT EXIST "%DIR%" (
ECHO Directory "%DIR%" does not exist.
goto END
)
setlocal EnableDelayedExpansion
set GB=
set SIZE=
set exp=000000000
FOR /R "%DIR%" %%F IN (*) DO (
set /a SIZE=!SIZE!+%%~zF
if !SIZE! geq 1!exp! (
set /a GB=!GB!+!SIZE:~0,-9!
for /f "tokens=* delims=0" %%a in ("!SIZE:~-9!") do set SIZE=%%a
)
)
if not defined SIZE set SIZE=0
if not defined GB goto EOS
FOR /L %%N IN (1,1,9) DO (
if "!SIZE:~%%N!" == "" (
set SIZE=!GB!!exp:~%%N!!SIZE!
goto EOS
)
)
:EOS
call :Divide !SIZE! 1024 SIZEKB
echo Size is: !SIZE!B (!SIZEKB!kB)
endlocal
:END
pause
exit
:Divide
set Num1=%~1
set Num2=%~2
set %3=
set Num=
set Number=
IF !Num2! EQU 0 goto :EOF
FOR /L %%N IN (0,1,18) DO (
if "!Num1:~%%N!" == "" goto :EOD
set Number=!Number!!Num1:~%%N,1!
if !Number! geq !Num2! (
set /a quotient=!Number!/!Num2!
set /a Number=!Number!-!quotient!*!Num2!
if !Number! equ 0 set Number=
set Num=!Num!!quotient!
) else (
if defined Num set Num=!Num!0
)
)
:EOD
if not defined Num set Num=0
set %3=%Num%
goto :EOF
10x faster than doing it through FOR. With the advantage of being able to use any of the permitted parameters of the DIR command (in this case /S)
