Answer 1

There are two issues here:

1. Your path is not specified correctly for a file: URL, which doesn't use Windows-style paths. Your path would be, I believe, C:/Program%20Files/Sublime%20Text%203/changelog.txt (see Microsoft docs).
2. Browsers are unlikely to open a file:/// link from a public web page without additional intervention from you (such as hitting reload or enter on the resulting blank page), as this would be a security risk. I've confirmed that Firefox behaves that way and I believe it's similar in other mainstream browsers.
