Relocated Item called swapfile0
Hi,
After putting it off for quite some time, I finally downloaded macOS Catalina. When it downloaded, I saw a new folder called Relocated Items. I opened it and apparently its for suspicious files or something. Then, I saw a folder called 'vm' in it, and I opened and saw a file called swapfile0. I'm not sure what this is, and I don't want to open it. I also have been noticing a lot of my accounts being hacked into recently so I think my computer might have a trojan. What is this and is it safe? Please reply asap thanks :)
