Owncloud introduced two features (I don’t know, if they are really ready to use) which seem to be very interessting. The first feature is called “Virtual Sync”. The second feature is called “Delta Sync”. Does anybody know if there are any plans to implement these features in a future nextcloud release as well?

Do a search this topic as already been discussed when the old bountysource get claimed. This feature will come in some future Nextcloud client updates. But for the moment the daily build of it is really messy and do not have this feature. You can install the Owncloud client if you wanna test it’s working. ---

Hi. is there any developments on this issue? I’ve noticed that nextcloud macOs client doesn’t supports virtual file or virtual drive. ---

No, Nextcloud have a problem with the dev of this feature, they have a lot of delay in it. Just be patient… that all we can say for the moment ---
