Hi,
It seems your machine is been attacked by virus and virus has renamed most of the real folder (Containing Data) and has hide them.
To find your folders open My Computer:
1). Goto "Tools" and select "Folder Options"
2). Now select "Show all hidden files and folders" under the available list.
3). Click on "Apply" and then click on "OK".
This will show you all hidden folders, however you need to remove the virus. I would like to suggest you to download MalwareBytes from below link:
