i NEED to verify if one FILE have dimension of 3056 byte before PROCESS it

if dimensio of file are different i need to stop process

thanks

ps. it's my first post so ... Hi All  in your batch, something like

if %~z1==3056 GoTo OK
Echo Error
GoTo :EOF
:OK
:: continue

%1 is the first param supplied to the batch and the ~z modifier returns the filesize in bytes

Grahamfor /F %%A in ("tps.bi_") do If %%~z1==3056 GoTo OK
Echo Error File Dimension
exit

:OK
...
...

file name are tps.bi_

this not work or i MAKE some wrong
for /F %%A in ("tps.bi_") do If %%~zA==3056 GoTo OK
Echo Error File Dimension
exit
 
K
...
...

this should work -- but why use a loop if there is only a single file ?
GrahamIf file.bin %~z1==3056 GoTo OK

echo Error File Dimension

goto warn

:OK
...
...

it's not work (i have try loop from one example)it's OK:
