Explanation:  The error occurred while renaming sourcefile_name to targetfile_name. Or, someone might have the target file open in a text editor.

Action:  Verify that targetfile_name does not already exist and verifythat sourcefile_name is not read only. Also verify that there is available disk space on the system. Verify that no one has the target file open in a text editor. If the target file is open, exit the editor and retry the operation.
