Soap Body contains only partial contents of file

Question

I have a VFS proxy in wso2 which is monitoring a folder. I have set the transport.vfs.Streaming to True <parameter name="transport.vfs.Streaming">true</parameter> But when I try to get the file contents I do not get the entire file content in my mediation flow

messageContext.getEnvelope().getBody().getFirstElement().getText();

This only returns half content of my file.

I tried setting the transport.vfs.Streaming to false still the same result
