Yes it is actually, though we would like our implementation to become a 
standard. [1]

Default XMPP file transfer isn't end-to-end secure as it happens outside the 
OTR layer. 

Our new file transfer implementation is an extension to OTR that allows for file 
transfer inside the OTR layer.

This means the file transfer is secured in the same way as the OTR messages. 
Unfortunately no other apps have implemented it yet.
