# Alternative software for processing Molden files?

I am trying to salvage old data, and one of my output files is in Molden format.

2. Is there another way to access Molden format files?

Thank you very much.

• @Mithoron no one in informatics will have an answer to this besides computational chemists there. This is the best SE to get an answer to such a question.

• @Mithoron In principle questions of this type are the reason for my newest meta discussion: What's our (maybe updated) take on questions about (quantum) chemical software?. Nov 14, 2016 at 8:31

• Even though ChemCraft does not open .molden files, it is able to open .wfn files. So if using ChemCraft (or any other .wfn-compatible software that can't read .molden files) is imperative, my answer might be helpful. Jan 20, 2017 at 19:11
In case you're OK with converting, Molden2AIM may be a good alternative. It is able to convert .molden files into .wfn files which are easier to handle in my opinion (the software actually does a bit more than just that, such as generating .47 files for NBO analysis).
If your .molden files were generated by ORCA, you may also try an automated script that handles the details of using Molden2AIM for you.
