File limits

As I don't have EP set up yet, I was wondering what are the limitations of shared files.

I know some portals have difficulties if single files are larger than e.g. 50Mb. We have extremely large files (well over 50Mbs) and it is important for me that the performance is not affected when working with large files.

Does this 50Mb limit applies to SAP EP as well, and if not, have anyone tested what are the "limits"?

Thanks
