I have problems with files not appearing in Windows Explorer screens. This has happened with Word .docx files and now a Publisher file I converted to PDF. I am using Office 2007. Acrobat 9 is installed - today updated to 9.4 Perhaps that is the problem and I should revert the drive to the way it was before the update. Is there a way to make sure that Windows Explorer is showing all the files in a folder. This one is there, Acrobat finds it in the Recent files list but I am not allowed to see it. Any ideas please? Paul.
