Solve : bat file - how to ignore window errors?

1.	Solve : bat file - how to ignore window errors?
Answer» I'm LAUNCHING pdf files within a bat file. I pass the instruction into bat file as a parm. It works great except for when the pdf doesn't EXIST and displays error window. Is there any way to ignore the error and don't display the error window? Is there a way to check if the pdf exist first before launching the pdf? The bat file has the FOLLOWING code: @Echo off start %1 EXIT The following is the nstruction sent as a parm: \\USDCAWS37750237\softwares\Temp\PDFs\CBL_2005.pdf Thanks, Alex(NEWBIE) [old attachment deleted by admin]Try using the IF command. Type IF /? at the command prompt.Your suggestion worked indirectly. I entered "IF /?" and it returned an syntax error displaying possible corrections which mentioned "Exist". The combination of "IF EXIST filename START filename" worked. Thanks for the tip! Alex
