PDF Comments Display

How does one get the PDF's summary comments to display.

With all other file formats, the summary comments show, but for some reason any comments I add to my pdf files do not display.

Any help would be appreciated....

Thanks

As far as I know you can't, as the pdf comments seem to be rather proprietary. However you can use Opus descriptions (File/File Commands/Set Description) to enter your own comments for any type of file.

Is there an example PDF file with some comments on the web somewhere?

Not that I have seen. But it is easy to do, if you really need it.

When I first saw this question, I went and made a PDF file with comments. DOpus shows that the file has a comment but cannot display it.

I don't find this surprising. Acrobat and other software embed comments in various ways. Even their own viewers cannot show the content of a comment.

It would be nice if DOpus could do this, but it is probably a step too far.
