< > |All other characters, including periods and spaces, are legal in Windows file names.Ch 2 26Using File Names as Using File Names as Variable ParametersVariable ParametersFile name reflects subject of file.File extension usually given by application creating file.Ch 2 27Using File Names as Using File Names as Variable ParametersVariable ParametersWhen naming files, many older 16-bit application packages adhere to older 8.3 DOS rules.Ch 2 28Using File Names as Using File Names as Variable ParametersVariable ParametersCan locate specific file by using file name. Give DIR command information about file you seek:DIR [drive:] [path] [filename] [/P] [/W]Ch 2 29Using File Names as Using File Names as Variable ParametersVariable ParametersIn some syntax diagrams you will see: [filename[.ext]]If a file name has an extension, it must be included.Ch 2 30Using File Names as Using File Names as Variable ParametersVariable ParametersA dot (.), delimiter, is used between file name and file extension.Example: MYFILE.TXTCh 2 31Activity—Using a File Name Activity—Using a File Name as a Variable Parameteras a Variable ParameterKEY CONCEPTS: System messages DIR command with long file names File extensions - more than 3 characters 8.3 file name Use of quotation marks Use of /x parameterHow 8.3 name derived from LFNReasons for keeping file names
