I'm trying to open a doc file written using RNFS. But I'm unable to open that file. When I try to open the file using the word application in iOS , I'm getting this error showing "Can't open file, file format doesn't match the file extension".

```
 var path = RNFS.DocumentDirectoryPath + "/test.doc";
 RNFS.writeFile(
  path,
  "Project Details\n",
  "utf8"
 );

```

But this is working fine in android.
