You're absolutely right, myFile.txt was a directory (who knew!?) So
now I'm making one instance of File and calling mkdirs on just "/
sdcard/zackcorp/myfiles/", and then I'm making a second instance of
File, this time with that path AND the file name, and just calling
File.createNewFile(), it worked perfectly.
Thanks very much for your help!
