How to open FoxPro files on my phone?

With the help of complex manipulations, I learned how to open FoxPro files on my phone. This forced me to work. I often have to make data "on the go." But I can't solve the complexity for several days already. I can't open the file because of an error that the file is not recognized. But I'm sure that before I had no problems with this file. Guys, I hope that you can offer something.
