Open Explorer- In the location bar enter C:\$Recycle.Bin and press Enter
- Click Organize
- Select Folder and Search Options
- Select the View tab
- Select Show hidden files, folders, and drives
- Untick Hide protected operating system files
- Click OK
You can also do this from the command line but the file names are encoded as explained in the linked article. When I tried this I noticed I could see more files than were visible in Explorer.
- Click Start
- Type cmd in the seach box and press Enter
- Type cd c:\$recycle.bin and press Enter
- Type dir /ah and press Enter to see all the available folders.
- Type dir *.* /s and press Enter to see all the files in all the available folders (with their encoded names).
