Sylvanus: Not sure if I understand your questions fully.

Any file can be "stored" in the brain. Importing? Depends what you mean. Brain can import certain application types, so it converts (maybe?), I don't use this feature.
- Is what you can install the programs in a folder on the brain for use later?
The registry of windows is it necessary in order to function properly installed programs in the brain?
Not sure what you are getting at. When you create a thought that is an application, you are really just creating a link to the application. So that when you activate (run) the link in the Brain it just invokes the application in the OS specific way. Thus, the target application must be installed in its normal way. I guess you could store a whole application inside the Brain, but that sounds cumbersome.
My goal is to have everything in my brain and that it is perennial, meaning that it is OK for the long term even if windows crashes.
I love the Brain and have been using it for years, yet I don't see how one can justify putting all your eggs in one basket. Baskets break.
I would like a brain that is independent of the operating system.
You will always need an OS. Do you mean one that is mobile? Like running off of a thumb drive?
