Delete zero size files in a drive eg:D:\ in win xp

Hai all,
is any bat file option to get all the file with zero size capacity in each drive in winxp drive so that these zero size files has to delete

please help me.

see here for vbscript solution. the other easier method, if you can afford to, is to use GNU find. (see my sig to download).

Code: [Select]

c:\test> gnu_find.exe c:\test -type f -size 0 -delete

Of course, if you want to use a pure cmd.exe solution, use a for loop with dir, then use  %~zI . see for /? for more info. OR search this forum.

C:\batch>type empty2.bat
@echo off

Code: [Select]

dir  /x *.*  |  find " 0 "  >  zerotxt.txt

for /f "tokens=5 delims= " %%i in (zerotxt.txt) do ECHO  "%%i"

rem for /f "tokens=5 delims= " %%i in (zerotxt.txt) do del /F  "%%i"

rem remove the rem from above  when satisfied  list is correctC:\batch>

Warning:  Be very careful with search and delete  from root down:  /s
cd \
dir  /X / s *.*  |  find " 0 "  >  zerotxt.txt

code will find nonzero files

Code: [Select]

S:>echo hello > "0 0 0.txt"

QED = "Quite Easily Determined"

Sezzz, the original poster,  requested how to find files with zero bytes and how to delete the files with zero bytes.

"QED" means "Quod erat demonstrandum" (Which was to be shown). It is usually placed at the end of formal proofs in geometry.

What about filenames with spaces?

Would "" help?

for /f "tokens=5 delims= " %%i in (zerotxt.txt) do del /F  "%%i"

for /f "tokens=5 delims= " %%i in ("zerotxt.txt") do del /F  "%%i"

no, because in a DIR listing, your token is the part of the file name from the first space to the second

I would rather get the file size directly from the FOR variable %%~zA

Hello

Yes indeed. Look forward to seeing your efforts.

Hello

I will allow Salmon Trout  the pleasure.

Code: [Select]

for /f "delims==" %%A in ('dir /b /s /a-d') do (
    if "%%~zA"=="0" echo File "%%~dpnxA" is 0 bytes
    )


Was Geometry  your last Math course?

No, calculus, but I remember QED mainly from geometry

Hello

if you use dir /b and %%~zA you don't need to worry about spaces

Hello

I use XP SP3 too and ('dir /b /s /a-d') worked fine. I don't know why it didn't work for you. One thing - if you scan a whole drive there may be a long time when nothing seems to be happening.

zerodel.bat

@echo off

set /a file=0
if exist "%temp%\deletions.bat" del "%temp%\deletions.bat"

        if "%%~zA"=="0" (
    set /a file+=1
    echo [!file!] 0 bytes "%%~dpnxA"
    echo del "%%~dpnxA" >>"%temp%\deletions.bat"
    )
    )
Echo.
Echo Deletions:

The above method delete files one by one. Not that its really a big deal, but a suggestion for a more efficient way, since del can delete multiple files passed to it on the command line, is to concat all the filenames into one string,  either by batches (or as many as del can take as input) and then pass it to del.
