If you are asking about the orphaned files, they are generally nothing to worry about. Anomalous shutdowns will often result in orphaned files (generally a file that still has a file record segment header in the master file table, but no directory/folder). Checkdsik will try to relocate orphaned files in the correct folder or even create a folder for them. Autocheck runs after most anomalous shutdowns to scan for such issues and, whenever possible, correct them.
If I were you I'd run a full scan:
right-click on a command prompt icon and open as administrator. In the command prompt window type: chkdsk /r (then press ENTER). You'll be told the disk is in use and asked if you want to run checkdisk on the next boot. Say yes, exit the command prompt window, and reboot.
