我想为（for）循环添加一个条件(i want to add a condition to (for) loop)

 在这段代码中它将pcap文件转换为csv，但我想添加一个大小条件 
 
 为了将pacp文件转换为大于或等于1兆字节 
 
 这是代码 
 
:START

set /a Old = 0
set /a New = 0
echo Counting files in folder..
for /f "tokens=*" %%P IN ('dir "C:\Users\..." /A /b') do (set /a Old += 1)
set Old
:: delay 120 sec
echo Delaying 120 seconds... (drop new file in)
timeout /T 9
echo Checking for new files..
for /f "tokens=*" %%P IN ('dir "C:\Users\S..." /A /b') do (set /a New += 1)
set New
goto COMPARE

:COMPARE
echo Comparing number of files
if %New% GEQ %Old% goto NEWF
goto OLDF

:NEWF
echo 
**for %%F in (*.pcap) do if not exist "%%~dpnF.csv" tshark -r "%%F" -T fields -E header=y -E separator=, -E quote=d -e frame.number -e frame.time -e ip.src -e ip.dst -e data.text -e  tcp.analysis.duplicate_ack -e tcp.analysis.out_of_order -e tcp.analysis.retransmission -e tcp.analysis.fast_retransmission -e tcp.analysis.spurious_retransmission -e tcp.analysis.zero_window -e tcp.stream -e tcp.srcport -e tcp.dstport -e data.len > "%%~dpnF.csv"**

goto START

:OLDF
echo No New Files.
echo Restarting
goto START
 
 我想在NEWF之后在echo中添加for循环条件 
 
 任何帮助谢谢 

in this code it converts pcap files to csv but i want to add a size condition 
 
in order to convert pacp file greater than or equal 1 megabyte 
 
here is the code 
 
:START

set /a Old = 0
set /a New = 0
echo Counting files in folder..
for /f "tokens=*" %%P IN ('dir "C:\Users\..." /A /b') do (set /a Old += 1)
set Old
:: delay 120 sec
echo Delaying 120 seconds... (drop new file in)
timeout /T 9
echo Checking for new files..
for /f "tokens=*" %%P IN ('dir "C:\Users\S..." /A /b') do (set /a New += 1)
set New
goto COMPARE

:COMPARE
echo Comparing number of files
if %New% GEQ %Old% goto NEWF
goto OLDF

:NEWF
echo 
**for %%F in (*.pcap) do if not exist "%%~dpnF.csv" tshark -r "%%F" -T fields -E header=y -E separator=, -E quote=d -e frame.number -e frame.time -e ip.src -e ip.dst -e data.text -e  tcp.analysis.duplicate_ack -e tcp.analysis.out_of_order -e tcp.analysis.retransmission -e tcp.analysis.fast_retransmission -e tcp.analysis.spurious_retransmission -e tcp.analysis.zero_window -e tcp.stream -e tcp.srcport -e tcp.dstport -e data.len > "%%~dpnF.csv"**

goto START

:OLDF
echo No New Files.
echo Restarting
goto START
 
i want to add condition in for loop in echo after NEWF 
 
any help thanks
