Hi @bb77, thanks for your reply.
Regarding accessing the files/modified versions with the nextcloud app, this does not work if the file type is not supported e.g. videos converted to h.264 encoded .mkv files (as I do to save space).
I opened another feature request for that: Media Type Support in IOS App
But even then this would render the iOS Photo app useless, which actually is pretty decent and more comfortable than the build-in nextcloud folder-views (especially the context menus for editing).
Regarding the bidirectional sync, I am not talking about ALL files, I agree that this is not what most users want. Maybe I should have made that clearer, sorry for the confusion.
I edited the first post slightly to make that a bit clearer, but don’t want to go overboard with editing the same post, so here are some more detailed thoughts on this:
I am talking about bidirectional sync just for the picture sync. If I take photos from different devices and upload them into a specific folder, I want to see them on all the devices and if I decide on one of those devices that a picture is no good and delete it, it should also be deleted on the other devices. That’s what I meant with it would generally make more sense from a logical use case, but also from a consistency point of view.
If you delete photos locally a bit after taking it (maybe because the picture was not taken sharp) you have to hope it did not get uploaded in the meantime, or else you have to go through pictures twice (locally and on nextcloud) to weed out the bad ones. If it would be bidirectional sync instead of pure upload the deletion would be synced as well.
That being said, I can see a use-case for people just uploading automatically and deleting locally for space (hopefully after making sure everything was uploaded correctly) and not going through the hassle of checking if unwanted pictures were synced. While i think that this approach just wastes space on the nextcloud and makes it more difficult to find the pictures you are actually looking for, I still think there should be a switch for upload/bidirectional in the settings to enable that use-case.
