Not getting XML files in completed interivews

Dear All,

I am using Kobo collect offline to do a small survey. In
this survey I am capturing just 2 Open end question, one GPS reading and 2-3
images. After few complete interviews, when I was trying to transfer data from Mobile to Laptop, I noticed XML
files are not present there however images was there.

Appreciate if someone can suggest how to retrieve those XML
files and reason for it?
