Do Seafile and Pydio support External Storage, similar to Nextcloud?

I’m thinking of moving off of nextcloud and onto something similar, so I’m trying out Seafile, and eventually pydio. I realized I mainly use nextcloud’s external storage feature primarily, as a means of accessing data from my home network share through nextcloud. free netflix tech news

it depends on which type of remote/external storage you are using,
but mainly i would say yes.
