Davinci Jnr 1.0 - how do I get compatible files?

[Roberts_Clif]

Thank you for the response.I have tried that but all it gives me in the drop down box is Project Files (*.3mf, *.amf) - there is no option for all files *.* (I am clicking on the small arrow and only the one option is coming up).Really frustrating - why on earth wouldn't I get the all files option???

Stated in post load a Project file though you have to import a STL files and other formats.
