A customer complained about this request and an enhancement request was created after opening a case.

To share multiple files to a community in HCL Connections Moile Application is not availble. We can share only one file at a time. For example, if we try to share 4 files from “My files” with an existing community we have to share every single file instead of marking 4 files and sharing them in one step.

If you think that this would be helpful please vote for this idea: https://connections-ideas.hcltechsw.com/ideas/IDEACNCTNS-I-2149

Thanks a lot !!
