Windows 10: What is :WofCompressedData?

I am trying to find out what WofCompressedData means.

I have made two posts on answers.microsoft.com, but I've never gotten a clear answer (http://answers.microsoft.com/en-us/w...5-b9cb5982f7ce ; http://answers.microsoft.com/en-us/w...3-a0e92467be5d)

A couple weeks ago, I did a MBAM Threat Scan on my desktop (nothing was found, I actually did a couple over that weekend and the following Monday as well... long story).

During the scan I noticed that a lot of the system files were appended with ":WofCompressedData" (or even with ":WofCompressedData:WofCompressedData") at the end. I wasn't paying close enough attention before, but this was the first time I have noticed it. When I re-ran the scan on my desktop I saw WofCompressedData appear a lot. When I ran the scan on my laptop, I saw WofCompressedData, but far less frequently. Both computers run Windows 10 64-bit and both of them came out to be clean. The MBAM people ran had me run logs, and they couldn't find anything wrong.

I wanted to know what WofCompressedData meant. On the first Answers thread, I was told "WofCompressedData file is a disc fragment file and can be deleted. This is created when virus scan is run on the computer." I asked them to confirm that there as nothing I should be worrying about with these files, but the user never ever returned to respond (and that forum doesn't have a private messaging system)

MBAM and Kaspersky and Microsoft Safety Scanner all do not find any problems on my computer. On the second Answers thread, I was told to run sfc /scannow, but the user there did not respond after replying that SFC did not find any problems.

I wanted to confirm that given all these clean reports that I should not be concerned about the ":WofCompressedData". Unfortunately, no one is giving me a clear answer (or sticking around after I reply)

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.

 

Maybe related to his? Do you have system compressed?

WofShouldCompressBinaries function (Windows)

Compact OS - Compress or Uncompress Windows 10 - Windows 10 Forums

Compression can be also used for backups. Windows has many of them enabled by default.

 

Hi:

Also, see here.

Do you think I have anything to be worried about or should I just leave it alone. I see it on both my laptop and desktop, but I find no evidence of viruses or malware on either machine.

My system is not compressed, but I do have System Restore points enabled.
