It is not possible to save the data obtained with NI myRIO.

Hello! Again, I ask for advice. I accept data from NI myRIO, then write them into an array and output them to a graph. Now my task is to save the data to a file. I used the "Write to Measurement file". I apologize if I did not understand the situation, I'm new. Thank you in advance for your help.

Think of the myRIO is a another computer.  It is an embedded computer.  Therefore it cannot save to your desktop.  What you need to do is make an application that runs on your computer that the myRIO talks with and saves the data.  Communication would be simplest here with Network Streams (talking over the WiFi or USB using TCP/IP).

There is a cRIO Developer's Guide somewhere on the NI site.  I recommend you give that a good look.

Here is the cRIO Developer's Guide for your reference: http://www.ni.com/pdf/products/us/fullcriodevguide.pdf (I would take a look at page 62).
