Clearing storage manually?
By error(?) during configuring Zotero after a new install I had also activated storage of attachments on Zotero storage, not only on my webdav server, as intended. Soon the Zotero storage was full and I got an error message about it. How can I manually clear it?
(note for others who come across this: Purge storage is otherwise very rarely the right answer, so don't use it if you're not 100% sure you understand it or if you've been explicitly advised to)
