Hello mjhoshaw,
Whenever you restore a backup, Hauptwerk will delete your existing cache files (because they may no longer be valid for the rank settings from the backup you restored), and then the first that you load any given organ Hauptwerk will automatically generate its cache file again. Hence when you restored the backup the free space would increase, then with each distinct organ you load the free drive space will drop again (because of its newly-recreated cache file). However, if your rank settings for any given are the same as before, its cache file will be the same size as before, so overall (after loading all of your organs again) the total space occupied by all of the cache files will be the same as before, and you won't have lost any drive space.
If you haven't changed your rank settings, and you still have as much free drive space as before, the reason that you are getting the warning about drive space now (whereas you weren't before) is simply because you upgraded the amount of RAM that your PC has, and Hauptwerk assumes that you might want to use most of it for Hauptwerk. However, you can just ignore that warning.
Edit: P.S. Aside from Hauptwerk, also note that with default Windows settings, Windows' page file will be on your C: drive, and its size may vary dynamically as you do things (in Hauptwerk or otherwise), affecting how much free space remains on that drive. Windows will also use the drive for its temporary files and other things, so drive space on the C: drive is likely to vary to some extent on a day-to-day basis anyway. Also (aside from Hauptwerk), Windows' page file size may be larger with larger amounts of RAM installed.
Best regards, Martin.
