I've been a user of NOF 9 for many years under Windows XP and happy with it. Recently I've moved to Windows 10 and reinstalled NOF 9 onto it. The product (NOF 9) seems to work fine on Windows 10 with one exception. Once I've made my changes to my website I can preview it in NOF 9 and it all looks 100% OK. However, I use a third party FTF software FileZilla for uploading it to the web. This has always worked perfectly under Windows XP but there's a problem under Windows 10 where some of the .HTML files are uploaded incorrectly:

FileZilla support people say it's "The Windows 10 virtual store". They claim that NetObjects Fusion 9 is too old and tries to save its files in a system-protected location and thus gets its disk access redirected to the virtual store.

I don't understand this explanation - can anyone explain why NOF 9 has this problem on Windows 10?
