old Quartus project files

I have to work again on an old project started 2004 with Quartus v3.0. Now I'm working with the actual v6.1. There are a lot of files in the project-directory :-((( therefore I want to clean up now.

does someone know, if the files with this extensions are necessary or old ones: project.csf project.dpf project.eco project.esf project.fld project.psf project.ssf project_assignment_defaults.qdf

I think, I only need: project.cdf project.qpf project.qsf project.qws

Is this right? I don't want to erase files, and recognize in a few month that they were necessary!

Thanks, Manfred

Hi Manfred, you should keep the project_assignments_defaults.qdf along with the cdf, qpf, qsf(s), eco, dpf and qws. I recommend backing up and archiving the other extensions just in case. The eco is used for logging operations done by the resource properrty editor and the dpf is used by the pin planner. The project_assignments_defaults.qdf is kept so that idf defaults change between releases, the set of defaults shipped with the version of Quartus when the project was first created, continue to be used for that project.

Hope this helps, Subroto Datta Altera Corp.
