Simple question, when you create a shared folder link you wil get something like:
Is it possible to change this to something easy to remember?
I am using NC 20.
Or is there maybe a different way to create a public upload folder with removal rights for everyone?
No such function exists in Nextcloud itself and is also no desired due to security concerns as you can read her.
Nevertheless you should check the app store for an app which provides that function. The ShareRenamer app is currently unmaintained but a Sharing path app exists which provide the desired function.
