I have being got confused because my program obtains filenames to
decompress programatically and they come with complete path, including
extension, while when I call the BAT from console I don't give the
extension. So:

c:\c>unzip32 -o prueba
Archive: prueba.zip
 extracting: ./prueba.txt
c:\c>echo %errorlevel%
0
c:\c>unzip32 -o prueba.zip
Archive: prueba.zip
 extracting: ./prueba.txt
c:\c>echo %errorlevel%
1                             <------------------ !!!!!

The problem is when you include the ".zip" file extension, unzip32.exe
changes its return code to 1 !!!

I don't know if this is a bug or a feature but it has bad colour for
me.

Thanks for your help.
