Limit to the number of files in a Realm?

[Daelda]

Is there a limit to the number of files (pictures/PDFs/etc) that can be in a single Realm? Lately I have been getting errors when I try to add PDFs or jpgs to my Realm. However, I have found that if I delete a jpg, I can then add in a new jpg.

I was trying to reduce the size of some of my jpgs as I was having crashing problems on my laptop and realized that some of my jpgs had not been optimized (reduced in size) like I should have done - which is why I was trying to put in new ones. In addition, I got some new pdfs released by the publisher and wanted to add them to Realm Works, but I keep getting "An error has occurred" when I try to add them. I know there is a file size limit - but these don't exceed that.
