Required Quartus files

[Altera_Forum]

My system recently crashed. However, before it crashed I had created the schematic of the CPLD I'm going to use and had a clean compile. I save all those files so I didn't have to do the layout again. I can open the project but come up with the message "Can't find design entity "jbe_1sec_timer" which isn't very descriptive. What are the main files I need to be able to reconstruct my previous work? Any suggestions would be helpful. Thanks...

I am not familiar with the schematics part of Quartus, but to compile you need the hdl files. That is, if I understand correctly, what the error is telling you. Somewhere in your design there is a 1 sec timer. (or something with a name closely related. This is an entity (building-block) of a circuit. Becouse this building-block cannot be found, the design cannot be built.
