Since there is no exact information related to this query, I advise moving the files to your SDcard. There seems to be a problem with the files and write operations in KitKat and because of that no application can manage the files on Android phones.
Install the application, then move it to the SDcard. Tap on app until the App Info appears. After the app has been moved to the SDcard, move the files in a custom folder and that's it.
