Browsers are sandboxed away from user storage.

You can change this by changing settings, command line arguments, build flags, etc. But can’t really expect people to do this just to use your website.

You can open a file for performant access in all major browsers. It's the same API used for uploading files (<input type="file" />), but you can also just load them into memory and do stuff.

Sure, with the caveat that the file is specifically selected by the user.
