Batch file - using a variable

@echo off
set filename = 
cd GWConfig_TDS-mtpe3003
set filename = VCU17_CCU6\applications\VCU17APP 
GOTO CHECKFILE

:CHECKFILE 
echo reached
IF EXIST %filename% ( echo exists 
) ELSE ( echo Doesnot exist )

///////////////////////////////////////////////

Here the output shows:

reached

Does not exist echo "exists" or "does not exist"

Something is wrong with the "filename" variable.

Besides,

@echo off
set filename = 
cd GWConfig_TDS-mtpe3003
set filename = VCU17_CCU6\applications\VCU17APP 
GOTO CHECKFILE

:CHECKFILE 
echo reached
IF EXIST VCU17_CCU6\applications\VCU17APP ( echo exists 
) ELSE ( echo Doesnot exist )

gives the result:

reached
exists.

There are two problems here. The first is a space after the variable name:

SET filename = whatever

it should be

SET filename=whatever


(Or you can use it %filename %

later, but that's just awful :)

The second problem is that without any quotes, your "IF" test will not work as expected if %filename%

empty. Instead of this:

IF EXIST "%filename%" ( echo exists
) ELSE ( echo Doesnot exist )

I don't have time to recreate this correctly now, but I can spot several potential problems:



  • Have you tried removing spaces around =

    in set

    :

    set filename=VCU17_CCU6\applications\VCU17APP

    otherwise you can have one space leading to your filename

  • You might want to quote the usage %filename%

    :

    IF EXIST "%filename%" ( ...
+2
