Doc Sharing & Macro Bug

Not sure if this is just a test bug, but in my doc settings I have:

%spinfolder-C:\Users\Administrator\Dropbox\SEO Tools\GSA SER\Doc Sharing\MoneySite\%

In that folder there are some pdf's.

See test window below. 

Thats no bug but the way it should be...spinfolder is giving the content of the file...so it is displaying this pdf content here.

If I place a pdf in here, it shows the pdf filepath and not pdf content. Surely it should do the same and show only the filepath for pdf field?

Can I use this macro here to select a random pdf from the folder?

next version will convert this to something readable. this macros however works as it should.
