Hi, just need to get the file size into a variable from a file set . And this file should be the latest in this set. I wrote a batch , but not working , could someone tell me why ? Cheers! Here is the code: @echo off setlocal enabledelayedexpansion for /f %%i in ('dir /od cT*a.log') do ( echo %%~zi setsize=%%~zi Pause )

set setsize=%%~zi

sorry , i pasted wrong without a space , but this still won't working.Thanks for helping me anyway : )

This is the corrected one , sorry ,but still could not show size value.@_@ @echo off setlocal enabledelayedexpansion for /f %%i in ('dir /od c:\T*a.log') do ( echo %%~zi set size=%%~zi Pause )

Why even bother with the DIR in the FOR? for %%i in (c:\T*a.log) do ( EDIT: Still, I don't know why you're using wild cards (implying multipule files) and using a standard SET. If you wanted the combined size, use SET /a size+=%%~zi. If you wanted last modified file's size only, use this: for /f "delims=" %%i in ('dir /od /b c:\T*a.log') do (

for /f "delims=" %%i in ('dir /od /b c:\T*a.log') do ( echo %%~zi SET size=%%~zi ) Still not working ?

There are only two reasons I see as to why this would fail: 1) The last name to be returned is the name of a directory (which always has a size of 0). 2) No files that fit the mask exist in that location.
