Can someone help me with FTS ADV 16 or 17(if they have released any updated version)?
Can not find them anywhere.
No. There are none and probably will not be released.
There is FTS ADV 15 that covers lots of topics (most of them are current). Current documentation of FileMaker is quite comprehensive and is useful for learning the tool. There are also video tutorials Tutorials on how to make an app — FileMaker Custom App Academy
The last (and still valid for much!) is FTS 15:
The link that jvagla posted is the latest "training material" and should be used. You can still get the 15 version for training the "advanced" basics!
