Autorun cd on windows xp

I think making an autostart.ini file will do the trick. For example, if the .pdf file you want to open on your CD is in the directory directory/to/ and the file is called file.pdf, you'd have to put the following int he autostart.ini file.

[autostart]
open=directory/to/file.pdf

Oh yeah, hopefully needless to say, autostart.ini needs to be ni the very root directory of the CD. :) Not sure if that is what you're looking for, try it out on a rewritable first to be sure.

thanks for your response.  I have been working on macs for the last 7 years and vey new to pc.  The problem seems to be with the compatibilty of the PT START application and the adobe autorun application with windows xp. I have tried both with the autorun.inf without success. Although the adobe acrobat application cd runs automatically.  I have looked at the programming on the adobe acrobat autorun but do not understand it in order to alter it to autorun my pdf file.  Also I am not sure about root directory, does that mean that the files need to be in the same folder on the cd?  I have copied files directly to the cd  without seperating them in to seperate folders.

File should be called autorun.ini and not autostart.ini. I think it should start from [autorun]. If Acrobat is installed on the computer and .pdf extension is linked to Acrobat, pdg file is opened when CD is inserted.

I have tried both autorun and autostart.  The software I have used successfully in the past was PT START with a autorun command:
[autorun]
open=PTSTART.exe double click for pace.pdf

I could try open=AUTORUN.exe double click for pace.pdf

Do you think that might work?

Don't answer that it doesn't work.  

I pasted into autorun the target of the alias of adobe acrobat reader  C:\Program files\Adobe acrobat 6.0\Reader\AcroRd32.exe and the file.pdf . This opened the file automatically from the cd.  This will be perculiar to my computer so how do I get around the fact that on someone elses computer acrobat reader will be either a different version or not in the same place?  I suppose I could include the installer on the cd so that it will  place acrobat reader onto there computer.  Will this autorun instruction work for each computer after installation?  Also when I use 'quit' from a form field I created in the pdf it only exits my pdf but keeps reader open.  Acorbat 6 does not seem to have a quit function on the menu. Do you have to press the x in the red box to close the program.

instead specify
open=Start file.pdf

thanks to all for the help.
leroyski, I used the autorun command to run reader from the CD
open=D:\acroRd32 file.pdf
your comments got me headed in the right direction

XP is tricky for a MAC user!
