Difference vdfx vs. vdf?

Post by kleemax »

I've searched both this forum and the online vensim documentation (8.2) but could not find any information on the difference between vdfx and vdf (appart from posts on compatibility issues).
Could you elaborate a bit as to:
a) what the difference is
b) your motivation for the change?

With 64 bit Vensim, models can get very large, to store the results of this we needed a new file format. VDFX can contain very large amounts of data (VDF was limited to approximately 2gb) and results are also now stored in double precision (rather than single with VDF).
