Warning: I have no idea what I am talking about.

Is it possible the EBooks app is just accessing the same pdf (rather than duplicating it somewhere else on the tablet)? If this is the case, the Ebooks app might allow you to delete the pdf from within the app.

If this is the case, there would be no reason to try to delete any pdfs. Both programs are just accessing the same pdf.

[I think a similar thing happens on my tablet when I clicked on a pdf. It opens up the same pdf in Adobe Acrobat (I think?). But this does not mean there are two copies of the pdf.]

I tried deleting the pdf's from within the EBooks app, but that also deleted them from MobileSheets.

A bit disconcerting.
