I read the list in digest form - sorry my response won't be threaded in properly!
How about this for your question, Idris? Pure DOS batch file stuff. I tested it with notepad instead of Acrobat, but I assume it should be close to working as shown here.
@ echo off
IF "%1"=="" GOTO NOARG
for /R C:\context %%n IN (.) DO IF EXIST %%n\%1 (
Echo Found %%n\%1
start Acrobat.lnk %%n\%1
GOTO END
)
:NOTFOUND
echo Couldn't find %1
GOTO END
:NOARG
echo Specify a file name to find
:END
