During a file-access or disk-access operation, for example, Open, MkDir, ChDir, or RmDir, the operating system couldn't make a connection between the path and the file name. This error has the following causes and solutions:
· The file specification isn't correctly formatted.
A file name 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 lists the explicit path from the root to the file. Any path that isn't fully qualified is relative to the current drive and directory.
· You attempted to save a file that would replace an existing read-only file.
Change the read-only attribute of the target file or save the file with a different file name.
· You attempted to open a read-only file in sequential Output or Append mode.
Open the file in Input mode or change the read-only attribute of the file.
