It is pure 'OneDrive' technology we are using, and so we are getting the best that MS provides in that respect - the cloud, their server hardware etc. - please do realise that the PDF file contains almost 900 (yes, nine hundred) pages. A total of 73 MB I think.
So my guess is that the size has a lot to do with the time delay we saw - as it was slow for me here in my office as well.
I will see if I can put up some program files - 'watch this space !'.
Thought so, but wondered. The 80MB wouldn't hurt me, being on a 400MBit cable the d/l shouldn't last longer than one or two seconds. In fact, it was fast enough. But simply to "open" the site lasted a lot longer, i didn't count, but it feeled more like 30 seconds... But never mind. I still wonder, when i shall find the time to digest 800 pages
