Partials can be saved as a .sdif file.
Choose File/Save Analysis As.../Save Partial Tracking As...

By default, the file will be saved in the Partials

Select a location and a file.
If no sound file is open, the corresponding file will be open automatically. If the file can't be found, AS will ask you to specify it.
If the current open sound file doesn't match the analysis file, AS will ask you to confirm you wish to use the current file, or open the original one.
