Where is the Save Setting being Stored?

Where is the Save Setting being Stored?

I applied the steps described at
https://help.zoho.com/portal/en/community/topic/how-do-you-to-sort-on-a-hidden-column-in-a-view#2266000001132452
that tell how to sort on a hidden field.

After several attempts, it finally worked.  But when I examined the .ds file I was unable to see where the change was made.  The script of the view looked the same before and after I did the save.

Can anyone tell me where this setting is being saved?  Is this setting only good for the user who is saving the setting (i.e., in a cookie?), rather for all users.

Thanks.
