Large ".reg" file support or REGHIVE support

[RealFX-Code]

Description of the new feature / enhancement

I would like the ability to import a REG file I have, (305MB). I also have those values stored in a REGHIVE file. Being able to preview those registry values before importing them to my system is very important for me.

Scenario when this would be used?

I use Sandboxie to install software, to then move them out of the sandbox to avoid malware.
Most software work fine without their registry values, but I found one that doesn't like that and doesn't work properly. So I do need to import whatever registry values was created by the installer.
