Using the size technique from tip 0494 and the ownership technique from tip 3109, I have scripted LargeFile.bat to report the ownership of files that exceed a specified size.

The syntax for using LargeFile.bat is:

LargeFile ReportFile SizeInBytes Path1 \[Path2 ... Pathn\]

where:

ReportFile is the path to a CSV file that will contain "Owner","Filename","size".

SizeInBytes is the file size that must be exceeded.

Path1 is the first path to start searching. The following are valid examples:

C:
"C:\Documents and Settings"
\\ServerName\c$\Users

Path2 - Pathn are optional additional search paths.

LargeFile.bat contains:

@echo off
setlocal
if \{%3\}
\{\} goto syntax
set reportfile=%1
if exist %reportfile% del /q %reportfile%
set size=%2
if "%size:~0,1%" EQU "0" goto syntax
if "%size:~0,1%" GTR "9" goto syntax
set /a size=%size%
shift
if exist %TEMP%\LargeFile.tmp del /q %TEMP%\LargeFile.tmp
:loop
shift
if \{%1\}
\{\} goto :finish
set SPath=%1
if not exist %SPath% goto syntax
FOR /R %SPath% %%a in (*.*) do call :parse "%%a">nul 2>&1
goto loop
:parse
set /a fz=%~z1
if NOT %fz% GTR %size% goto :EOF
set file=%1
set rawfile=%~nx1
set owner=
for /f "Skip=4 Tokens=3*" %%b in ('dir /q /a-d %file%') do if not defined owner set owner=%%c
if "%owner%"=="" goto :EOF
call set owner="%%owner: %rawfile%=%%"
set owner=%owner:  =%
set owner=%owner: "="%
@echo %owner%,%file%,"%fz%">>%TEMP%\LargeFile.tmp
goto :EOF
:syntax
@echo Syntax: LargeFile ReportFile SizeInBytes Path1 \[Path2 ... Pathn\]
if exist %TEMP%\LargeFile.tmp del /q %TEMP%\LargeFile.tmp
:finish
if exist %TEMP%\LargeFile.tmp sort %TEMP%\LargeFile.tmp /O %reportfile%
if exist %TEMP%\LargeFile.tmp del /q %TEMP%\LargeFile.tmp
endlocal
