How to save to file from forms

Can anyone please help with one problem.
I want to save values from ui-form`s to file, and when i insert new value from form A , value from form B will stay unchanged. Can anyone help with function/flow ? Later i want to read from file and use these value as a global

Why not have one form that keeps its values.

[{"id":"c6319a103f275834","type":"ui_form","z":"65617ffeb779f51c","name":"","label":"","group":"2d4fe667.28f8ba","order":23,"width":0,"height":0,"options":[{"label":"value a","value":"q","type":"text","required":true,"rows":null},{"label":"value b","value":"b","type":"text","required":true,"rows":null}],"formValue":{"q":"","b":""},"payload":"","submit":"submit","cancel":"cancel","topic":"topic","topicType":"msg","splitLayout":"","className":"","x":190,"y":3780,"wires":[["6850302ade08b95c","db10faec44b52d10"]]},{"id":"2d4fe667.28f8ba","type":"ui_group","name":"demo","tab":"1caa8458.b17814","order":2,"disp":true,"width":"12","collapse":false,"className":""},{"id":"1caa8458.b17814","type":"ui_tab","name":"Demo","icon":"dashboard","order":1,"disabled":false,"hidden":false}]

How to import a flow

Case is that i need few separate forms....

You need a context variable that collects all of the form inputs. Then when a msg arrives, you will need to get the context variable, update the appropriate property of the variable and then set the variable with the new data.

Or a join node and feed forms back to the join and use msg.complete to submit the changes
