I have not seen a single file. The only thing I can tell you about the following restrictions:
1. Base in 130GB for one wokrspace (and hence the model). If there is an option for HyperModels, then this bar will be higher.
2. 2 billion cells per line item.1
the 130GB limit doens't mean much. I'm not saying it's not a limitation, but it cannot be compared against a file size or a hard drive storage.0
