To exit Quantify, select File > Exit Quantify. If you analyze a dataset interactively, Quantify does not automatically save the last dataset it receives. When you exit, you can save the dataset for future analysis.
By default, Quantify names dataset files to reflect the program name and its run-time process identifier. You can analyze a saved dataset at a later time by running qv, Quantify's data analysis program.
You can also save Quantify data in export format. This is a clear-text version of the data suitable for processing by scripts. Read Exporting performance data and Saving data incrementally.
