If exist
is what you need. Here is an example:

*IF EXIST c:\autoexec.bat echo Yupper

*That is a simple example. For "echo Yupper", you can substitute something
like "copy x:\my.dll %windir%/my.dll". You could also get fancy, create a
label in the command file (e.g. a line that begins with a colon immediately
followed by a label) and jump to it, like this:

*IF EXIST c:\autoexec.bat goto mylabel
echo Nosireee
exit

:mylabel
**echo Yupper
exit
*

hth,
Arthur
