Where I get hazy is this:
Ah.
Problem B.
Apologies.
I know that with a simple browser download once you click a link, right click save as etc the browser already starts to download header the file. It gets header data and all that. Which is fine since I want to download the file it can start downloading into cache while I name it and choose the save location. I was not aware that this is standard behaviour within all browsers. Makes sense.
However if I use IDM and the IDM dl box pops up and I select download later - at 01:00 for example - I don't expect the browser to download that file into the browsers cache as IDM will be doing the download.
If I download an iso file with IDM the browser will literally download the fulle 2gb file into cache and IDM will download it again. This is where NetWorx comes in as I monitored the data throughput to confirm the browser was downloading into cache.
My only way around this is to right click the link and download with IDM. If I left click and IDM intercepts I basically use double the bandwidth as it downloads into cache if I keep the browser open.
Hope the above was clear enough. I know...very confusing issue. Again this was not the behaviour previously as I queued up 10's of gbs during the day and my cap would have been depleted fast being on 100mb/s line.
