There's no limitation on uploads or downloads other than what your DNN instance is configured for via the web.config and portal options.
Just note that the downloadable products functionality in this store is very basic and I advise checking it against other products to determine suitability.
The docs page has some information:
https://nbstore.codeplex.com/wikipage?title=Downloadable%20Products&referringTitle=Documentation
Also note that this store is out of development, although it currently still works as designed. This may not be the case with future DNN or IIS/MSSQL changes.
