changing file extension from ".rte" to a .rvt file

[Archiez]

Hello,
I am using the student version revit 2017. Apparently, I started my file as a template file, ".rte file" and now that I have most of my work done, I am unable to set up central model sharing for my partner to edit. Ive tried switching the extension name, by renaming to .rvt, "project file". However, when I attempt to open the file, it will not open. I get an error message stating file is not valid, and to rename back to .rte. I don't want to create a new file, or attempt to copy and paste and risk having to start over. What can I do about this?
 
 
Thank you.
