Time Line for Windows can open and consolidate data from On Target files. It is important for you to understand that once the On Target file has been saved as a Time Line for Windows file, it is no longer readable by On Target. Time Line for Windows can consolidate data from a file or task in On Target without changing the structure of the On Target file.
For more information on using Time Line for Windows and On Target together refer to Chapter 10 in the Time Line for Windows manual.
