Chrome is free, and I use it all the time now. As Microsoft keep getting in the way with their Edge, and Onedrive, which I really don't want, I do everything with Chrome docs and spreadsheets for nothing! You can uses their Onedrive to store all these online and unless you put all those - er - videos there, you get a huge amount of free space!
I keep all my photos on an external hard drive,to save getting 'reminders' from MS too!
Goosey, Chrome is dead easy to use! I don't know about online auctions, as I only use Ebay for that, but there might be a need for sharing a file over Chrome which again is very easy, and saves adding attachments etc.
