I accidently pressed something, but luckily for the good. My documents are now under separate file types represented by icons. I am now more aware of what is actually in my documents folder. One icon is titled Cascading Style Sheet Document. I can make out some of the words, which tells me the cascading file was created when I bought some moth repellent a few years ago.
Q1: Can I delete it?
Q2: How did it get onto my computer?
Q3: I have purchased quite a few things on line, why aren't there other cascading files for my other purchases?
Please be aware, when it comes to computers, I know nothing. I have tried to look the answer up on line but cannot understand any of it.
