Finding it hard to reconcile my down/up loads with my billing (Orcon 30/10 fibre)). 

Twice I have recently updated comps from win8 to 8.1 and have seen a 8GB spike in my usage both times. 8.1 is 3.6GB and if you add 400MB for other updates you get approx 4GB. 

I have also recently synced 13.8GB to my Google Drive and saw a 20GB spike in usage for that day.

Does this seem OK? Just wouldn't have thought overheads would have added so much.

protocol overheads won't account for anything like that level of difference, but it's essentially impossible now to actually be aware of all the traffic flows on a typical PC, let alone a typical LAN/WLAN.

There will be other things doing traffic as well you're not aware of.

I remember the day when I understood what literally every file was on my computer - today I barely understand what version of windows is installed :-)

I would expect overheads around 10% but not what appears to have been added.

The first spike is for the 8-8.1 upgrade and it is over 9GB. The next big spike is 23GB for the 13.8GB upload. Just seems weird. I am the only one using the network, so know what is going on, and the other daily amounts are pretty indicative of normal activity. 

And, as I said, last month I had the same 9GB spike for another 8-8.1 upgrade.

So, really can't blame overheads can I?

Must be some explanation but I am struggling to think of one.

Neil, I am sure you are not alone in not knowing every file on your comp. I only know 90% of them, now:)
