or all other Word.doc files?
If it is just PDF then I am not sure, but for all Word files you can find the defaults in Tools > Options. I can't tell you where about in Options because I'm not on my computer that has Word on it at the moment, but it is there somewhere.
When I open a word document in Preview and go to convert it to a PDF
Adobe PDF (Convert to adobe pdf) it automaticlly says "save in - Temp folder. I want this to automatically save in "a dedicated folder" which I have set up. Can I do this. Where do I look for the setting to change the default Temp folder
