Windows 10: Invisible file in /Users file

Hello, I've attempted to move some files from C to D, after some moving I've checked my user file and I used to have 2 files, which were "Public" and "robim" lost file, the robim file was not there.I've checked for this file in %USERPROFILE%, and it still appears to be there, yet when I click back to Users,

:)

 

User can't copy files from network share. Permission error.

Seems security essentials wasn't liking the file for the user for some odd reason. Thanks for your suggestions.

 

Hard drive filled with invisible files.

My C:\ drive, which holds the Windows 10 OS, programs data/files and a little bit of user data, shows that I have used roughly 600gb of space (first image below) on a 1TB SSD. When I use WinDirStat to see what's on that drive, it shows that I have about 120gb of data on it (second image). Could someone kindly suggest what could be taking up 480gb of space—and why it is invisible to WinDirStat. Your help would be greatly appreciated.

...

you get the idea. ( too lazy to put it in a for loop and test it.

or just open regedit and remove all the fileX from that key.
