I view the /data directory. Is there a way to use windows explorer when the
phone is connected or anything?

Maybe that's a permission issue. Astro File manager is not allowed to
look at your app's local data (data/files in its sandbox).
However, why don't you just read the contents of the text-file you
wrote? If that's successful, writing to the text-file was successful
too.
