How do you prevent thumbnails from being created when a container has a PDF? Dragging or dropping or inserting a PDF into a container creates two files; a PNG and a JPG. They take from 80k to 150k per file and I do not need or want them. I cannot imagine scanning 10,000 PDF documents for storage and ending up with 30,000 files and an lot more storage.
I have unchecked generating and storing thumbnails. These do not seem to be thumbnails as they are full size (letter) and 72DPI. If you manually delete these files then you get an error message in any container. The containers are set for PDF files.
