In Windows 10, I can encrypt the entire hard-drive with bitlocker. However, it makes some programs run too slowly. In fact, most of my hard-drive is not secret: these are just data files and documents that I intend to publish anyway. The only thing I can think of that is really secret is the file in which my browser keeps the passwords. For such a small file, it seems wasteful to encrypt an entire hard-drive. My questions are:
Are there other parts of a standard Windows system that should be encrypted, besides the browser password file?
What is an easy way to encrypt only those files, while keeping the rest of the hard-drive unencrypted and fast?
