Path File Access Error

During a file or disk-access operation, the operating system could not make a connection between the path and the filename. 

• The file specification is not correctly formatted.A filename can contain a fully-qualified (absolute) or relative path.  A fully-qualified path starts with the drive name (if the path is on another drive) and then lists the explicit path from the root to the file.  Any path that is not fully-qualified is relative to the current drive and directory. 
  
  
• You attempted to save a file that would replace an existing read-only file.From Windows Explorer, right-mouse click on the file, and select Properties from the pop-up menu.  From the Properties window, change the properties to enable read/write capability.
