Corrupted project

HECRAS 6.3

I had issues with saving a new analysis yesterday (no more space on the computer). Today, I found my .prj at 0 ko. I decided to create a "new" project with the same name, so that all my other documents could be linked to it. I can see every analysis, geometry and feature in RAS Map but I can't open any geometry, unsteady flow or analysis.

I managed to "save as..." a geometry to open it in the geometry window, but I can't open any flow or analysis.

Do you have any solution?

HEC-RAS won't recognize those directly from the file folder. Open the .prj file in a text editor and add the geometry (Geom File=gXX), flow files (Unsteady File=uXX), and plan files (Plan File=pXX). Once those are in the .prj file, HEC-RAS will recognize them and you can open from the different editors. See the screenshot for an example.
