Description

Feature request

I'm running version -> Nextcloud Hub 9 (30.0.0)

I have a large folder with photos, that I've shared to various other nextcloud users.
In the filesystem the photos exist only in my account. The other accounts that I've shared the photos with don't have any physical files.

When I now start the preview generator, then it generates previews fot these photos for ALL users that the photos have been shared with. In my case this is a huge waste of harddisk space.

In an ideal world I would expect that previews should only be generated once for each physical file and if that file is shared to another account, then also the preview should be shared along with this photo.

Is there a way to achieve this or would this only be possible if the preview generator would be part of the nextcloud core?

Kind regards
Christian
