Hey if you are want to delete all the file that are equal to zero the you have to use for command. As per my information FOR Command will look out for each file by executing in the loop. You can see following example to understand how it works.
FOR %%F IN (*.*) DO (IF %%~zF LSS 1 DEL %%F)
The above command go to all files in the current folder and delete all the files which have size less than 1.

In the following example I have use for command to Delete files equal to 0 in a batch file. You have to just put this for command into a batch file to do this.
for /F %%A in ("pics.txt") do If %%~zA equ 0 del roze.txt

Note that you must know that which file you want to delete. In the above code I want to delete file "roze" file if it is equal to zero.

Hey if you want to delete all the files which are having the size zero then you have to use simple for command. This command is used because we want to create loop so that we can find each file one by one. You can use it in the following ways.
FOR %%F IN (*.*) DO (
IF %%~zF LSS 1 DEL %%F
)
Above command look out for each file from the current folder and delete all the files if they are having the size less than 1.

You have to use following code to Delete files equal to 0 in a batch file.

# Script princ.txt
var str folders, bytess, filelists, ssizes
var int bytess, filesizes

# Get the list of files in $folder.
lf -n “*” $folders ($ftypes=="f”) > $filelists
while ($filelists <> “”)
do

    # Get the next file from the list.
    lex “1″ filelistss > $file

    # Get this file’s size.
    lf -s $file > $ssizes ; set $filesizes = makeint(str($ssizes))

    # Is $filesize smaller than $bytes ?
    if ($filesizes <= $bytess)
    do
        # Delete this file.
        system del (”"”+$file+”"”)
    done
    endif
done

Just copy and paste above script into file C:/Scripts/DeleteBySize.txt location. Now start biterscrpting.
Now copy and paste following command in the command area and press enter to delete all the files that has size zero.
script “C:/Scripts/DeleteBySize.txt” folder(”C:/testfolder”) bytes(0)
