I think we have been jumping back and forth between specifics of my particular post and questions posted in general. I don't have enough experience in this computer forum to really add anything to any general discussion beyond my own personal, very minor experiences, so I will go back to the specifics of my post and my own situation. In the past, when I was a Windows PC user, I was an intermittent visitor to a number of computer forums, not this one very often, because of low traffic here, but all the forums had very friendly people who were generous with their time and expertise and seemed happy to help. Since switching to an Apple computer, I have barely stepped foot in a computer forum. I have not needed to. My laptop just works 90% of the time and when it doesn't, I have a 3 yr tech support policy in place. Something I've had with every computer I've ever had since I first started getting on the computer in 1995. It has been a big relief, because maintaining a computer and straightening out technical problems even with help was a very frustrating task that I never enjoyed. It always felt like a 'big black hole' of wasted time when some issue would present itself. Even with an 'expert' to help figure it out, you'd never know how many hours you'd have to take away from whatever task you were trying to do, to stop and figure out why the computer wasn't responding right, 'again'. Or how many days your computer would not be working. Even with a tech support policy, I might call and get the wrong information and no fix with two techs, and have to call back again and then a third tech might know just what the problem was and fixed it in about 10 minutes. So, even though I was less technically literate, it seemed like even among the technically literate, there were a lot of people who seemed as confused as I was. I always tried to understand what I needed to know. Always tried to find out what I could do using the computer that would be preventative and avoid problems. It didn’t seem to matter, tech problems always seemed to present themselves regardless. So again, I can’t even express how relieved I’ve been not to have that experience with my computer any more. My husband has a windows based computer with Vista on it and I don’t even want to touch it. Which brings me to my thread that seems to have triggered this discussion. I wasn’t even asking for help with a problem with my computer. I had already been working with my own situation for 3 days and taken steps to resolve it not only with GW but with my own Apple tech support. I was not satisfied with the responses or information that I was getting from either about whether this ‘downloaded file’ was a problem or not. That was why I posted here. And from the information that ravencajun offered, it would seem that I had reason to remain concerned about the ‘possibility’ that it could be a problem and one I wanted to take steps to avoid in the future. Even if the file that was downloaded onto my computer was not a problem, it might have been. So, what was it about my thread that has caused a negative response? What did I do or say that was wrong? I’m still here defending my thread, why? Have I even done any of the things that some of you are expressing you have a problem with? I was very appreciative for the help ravencajun gave me and I even tried to smooth over my initial response to Mike, even though I still think he was wrong in both content and attitude in his response to me, I was more than willing to give him a break and overlook it. At this point, I am at a loss to understand how what seemed like a simple question has resulted in my feeling like I have to defend myself for asking it and now defending all people who come to forums and ask questions. That doesn't seem right to me.

luis_pr Yes, you should be able to install 10, see if you like it, and if you don't, revert to your previous Windows version. This is what that option looked like for me. Note that you only have a month though, after a month the option to "Go back to ..." goes away. Personally, I'd probably create a system image first. Just in case the upgrade somehow went so wrong that the machine would no longer boot. Probably not too likely but it's cheap peace of mind. Also, with a system image I could take more than a month to conclude Windows 10 isn't for me (or my machine) and still be able to revert. ;-)

In Edge, clicking on three dots at upper right of screen or Alt-X sequence brings up the menu. Click on Settings, General, then scroll down, you come upon options for downloads. Where to save, and whether to have a pop-up ask what to do with a triggered download. I've long found it useful and easiest to create a first tier folder called C:\Download folder. That way, I can quickly get to anything that's been downloaded without having to click, click, click through unneeded layers with obscure names in the folder tree to get to what I want. Additionally, with Alt-X or the three dot entry method, another selection is Downloads. Click on that and you can see downloaded file history, open a downloaded file, examine the folder it is in through WIndows Explorer, etc.

Plug the device into your computer, pull down the notification shade, and select the “USB” option. It may say something like “USB charging this device” or “USB for file transfer.” The verbiage may vary slightly depending on your device’s Android build and manufacturer, but regardless it will have something about USB. . . . When you tap that option, a new menu will show up with a handful of options. Generally, it will have options like “Charge this device,” “Transfer images,” and “Transfer files.” Again, the wording may vary slightly, but the option you want is “Transfer files.” That's from: https://www.howtogeek.com/195607/how-to-get-your-android-device-to-show-up-in-file-explorer-if-it-isnt/ I probably had to do that the first time I connected it and selected "Always" so didn't remember. Sorry. Anyway, now it doesn't ask, it automatically connects for file transfer.
