Max file size

[aliakhavan89]

I’m trying to export sensitivity .vdfx file to .tab. Is there a limit on the file size of that Vensim can handle?

I’m using a command script within a python workflow on windows and so far it can’t go beyond 5 GB .tab when exporting a 1 GB vdfx.

Everything is done locally (no Dropbox) and I’ve tried on SSD and HDD. I have more than enough storage, CPU, and RAM. Just want to make sure that Vensim is not the bottleneck.

In theory there is no maximum file size. It's going to take a lot of time though to export something that size.

I don't mind waiting if it is in the order of a few days. But sometimes, Vensim returns 3221226505 instead of 0 and that's why I was suspicious of the file size. So I guess it might have been successfully completed in the first place.

Do you really need to export the whole file? You can use a savelist to export just the data you need.

I'm just saving the data I need. It's more than a hundred thousand simulations; even with save per 1, it's millions of data points.

I think the 3221226505 return code may be a variable type mismatch - this has been reported in other contexts.
