Load data from txt file to edittext

Good morning everyone,

I'm working on a Matlab GUI composed by around 35-40 EditText which will be used to insert the input data necessary for executing some jobs.

Here's my problem: since the Input data number is quite high, it should be possible that the user hasn't all the data at the same time, so he needs to save the data already entered and then reload it for completing the insertion in a second moment.

I've already done the "save" function which writes down data in a .txt file, now I've to write the "reload" function, which basically brings data from the .txt file and put the values in the GUI EditTexts already compiled. Is it possible? Any suggestions?

Thank you all in advance,

Mattia
