Windows 10 - Explorer is no longer showing files on my phone when it is connected to my PC

[Windows Central Question]

Windows explorer on my Windows10 PC used to show the usual files on my phone when I connected my Lumia 1020 to it; Documents, Downloads, Music, Pictures, Ringtones, Videos.

I can't quite work out when it stopped doing this but now it seems to show all the background system files; AppInstall, CommonFiles, Critical Data, Data, DPP, EFIESP, MMOS, PreservedData, ProgramData, PROGRAMS, System Volume Information, test, USERS, Windows, WPSystem.

Please can someone tell me how to change it back?

A reason I could think of is that somehow the folder attributes got changed and the usual folders like 'Documents' etc. got hidden and the hidden system folders got visible (sometimes a malware or a virus can do this). To change it back, connect your phone, view all hidden folders and system files in the Windows Explorer, and change the attributes back to proper state. To do this, right click the folder and click 'Properties'. At the bottom of the 'General' tab, you will see attributes. Check/uncheck the 'hidden' box.
