How to retrieve files under folders with v2.0

Hello all,

I'm trying to retrieve files under folders with v2.0 of the API. This is currently not documented.

Any hint would be appreciated. I already tried the parameters used in v1.0 but this seems not to be working.

Also: How do I retrieve workspaces? Currently, the workspace "My Files" seems to be the default and I don't see any possibility to change that.

Thank you for your help.
Best regards
Norbert
