So... today I did a manual cache clean-up with the help of a YouTube video from the "Britech" channel. It made me SO NERVOUS to do this, I thought I was going to have a cardiac arrest! But, so far at least, it all seems to have gone well. And I learned some new stuff along the way too.

By the way, in case anyone is interested, as mentioned above I had previously downloaded & run the free version of CCleaner. However performing a manual cleaning removed a lot more extraneous stuff than did the free version of CCleaner.

Here's a link to the Britech YouTube video I followed:
