Cause analysis, because the buffer file is generated during the editing process. If ": W" is not executed, and the network connection is disconnected, A hidden file ending with the file name SWP is generated in the current directory. Deleting this file will not trigger an alarm if you use VI again, but the file will be rolled back to the status before editing.
