Someone please provide the QFS filesystem download link here.
I tried to download from the below link, but it is not downloaded for me, instead it redirects to some other page.
The link works just fine for me.
When I click on "Download Now" is correctly redirects my web browser to:
which is an announcement that you can't get the software from your link any more.
That link I've provided tells you clearly where to go for downloads.
Keep in mind that not all of the software that Oracle now owns is available for free even if it was free from Sun. Sun doesn't exist any more. Oracle chooses what is available and where it can be found.
