-NO mimport option

The no overwrite (-NO) option of the mimport utility command is used to indicate that an existing imported mms file (.mms) is not to be overwritten. If the no overwrite (-NO) option is specified in the command line of mimport , and if the file with the name of the map resulting from the imported process file exists, it will not be overwritten, the map importing will fail, and the Map Import error - The imported map source file cannot be overwritten, file already exists message will be written to the mimport log file if enabled. If the (-NO) option is not specified, the file with the name of the map resulting from the importing process will be overwritten.
