Windows 10: Files Disappearing

For some reason files have been randomly going missing on my computer. One day they're there, and the next gone. However, when I looked in my "recently opened" the files are there, but I couldn't open them because they had been "renamed or deleted". After this happened I thought it might be something to do with hidden files so I went to the directory where those files were and under attributes checked "Hidden files" after un checking it though I can't see any of the files that were there. I went refreshed my file explorer and even reopened it but now they're gone. Now I have two problems.

Downloaded files disappear


When you download a file through any browser, there's an option somewhere to 'Open Containing Folder.'

In Windows, to find a file you have downloaded...

1. Open your personal folder by clicking the Start button and then clicking your user name at the top of the Start menu's right pane.
   
2. Double-click one of the following folders:
   
   • Downloads
     
   • Documents
     
   • Pictures
     
   • Videos
     
   • Music

If you do not see the file you are looking for, but know its file name, you can search for it by following these steps:
To search for a file you have downloaded...

1. Click the Start button
   
2. Type all or part of the file name into the Search box.
   The file you are looking for will appear in the list of results.

The option converting m4a files to wma files in windows 10 is disappeared

• What app are you using to convert the files?

I don't use any app to convert the files. I just copy the m4a files from my music folder. Then I paste the m4a files in my android phone drive that connected to my laptop. Then a windows pop-up that shows the option converting m4a files to wma files appears.
You can see the windows pop-up in below picture. Now the windows pop-up is disappeared.

• Were there any changes made to your device prior to the issue?
