The size limit of point cloud file attached into microstation

Recently, we are using microstation to view point cloud files. The type is e57.

Size of the e57 files are not fixed, and could be more than 10GB. It worked fine when I tried with a 11GB file.

So is there any designed size limit of point cloud file, that to be attached into microstation?

Our microstation edition is 10.10.00.23

Thanks.
