Specifying a Filename

You specify the name of the log file with the LogFileName property. You can specify any value for LogFileName, including a directory path, provided the filename is supported by your operating system. Additionally, if LogToDiskMode is Index, then the log filename also follows these rules:

• Indexed log filenames are identified by a number. This number precedes the filename extension and is incremented by one for successive log files.
• If no number is specified as part of the initial log filename, then the first log file does not have a number associated with it. For example, if LogFileName is myfile.daq, then myfile.daq is the name of the first log file, myfile01.daq is the name of the second log file, and so on.
• LogFileName is updated after the log file is written (after the stop event occurs).
• If the specified log filename already exists, then the existing file is overwritten.
