Windows 10: What is BGMA3WMK?

I was trying to download pics from my fujifilm camera to my pc and I got a file that wouldn't copy quickly. The prog said it would take over an hour.

So I aborted that 'batch' copy and went for a single drag and drop copy and I got a message that it was 'downloading to BGMA3WMK' ?

That turns out to be a directory: '... Inetcache/IE/BGMA3WMK'

What on earth is all that about?

Apps not closing, still running in background

Thanks for the response. I am not looking for a "close all" function. Sometimes I intentionally want to leave an app running. In windows phone 8.1, I could exit and close th app by merely selecting the arrow/back button, I am looking for that same functionality.
When I'm in an app, I want to be able to exit directly from there and not have it continuing in the background.

 

Apps not closing, still running in background

I just got my Lumia 950 phone. On my prior Windows phone, when I pressed the arrow/back button on the bottom left screen, I would exit the app. On Windows 10 phone, I've been doing that and I just realized I'm not exiting the apps. I had intentionally not
exited an app (because it had my boarding pass). Instead of back button, I pressed the middle window button. Later when I went back to call up my airline app, I pressed the arrow/back button and held it. Similar to my old windows phone, it showed me all the
apps that were open. SURPRISE! unlike my previous phone, no app had been closing. Right now, I can't seem to find a "one click" way to exit an app. The only way is after I've done a few things, I hold the back button and click the "X" on each of the open items.

Can someone tell me how to exit an app with one click or swipe so that it is not still running, i.e. when I press the back button I will not see it? I'm sure this is something simple. I search the instructions that came with the phone and looked in the
forum but haven't found the answer.

thanks in advance the assist.

 

Inetcache is Edge/Internet Explorer cache folder.

 

thanks for that. looks like IE is active even though I never use it, never click on it. wonder how it got involved in a simple drag and drop operation between folders? hmmmm... curious...
