DEL "\\.\C:\FILE000D.CHK\FILE000D" but I get an answer that it wasn't deleted
What should I do now?
The C:\FILE000D.CHK\FILE000D is created when you run check disk (I believe) with a fix option and is a Recovered File Fragments, so it may be viewable with a text editor, but I can't see why it can't be deleted. However, I don't believe it is harmful, just strange.
If you can see the file in the windows explorer, right click on it and select properties, it may show it as read only hidden and archive. If you can reset the attributes to just archive, you may be able to delete it.
