I tried this, with using the test.txt in my resources directory and also writing a file to the applicationDataDirectory. The only way I made some progress was in the resources directory and just using TiFtp.write('test.txt'); but a file in created on the server, but it's empty. Any ideas? (I know this is an old gist ;) )
