it depends on what you mean by that: The complete disablement of any archiving Alfresco does or just hiding the Trashcan from the user interface? In case of the first option, do you want that to apply to every piece of content or just within a specific context / for a specific type?
I have this same desire. Delete should delete and not archive (globally, no exceptions). I tried adding this to the alfresco-global.properties file: system.content.eagerOrphanCleanup=true
But that didn't help. I still see the files in the "Manage Delete Items" via Explorer waiting in the recycle folder.
it is not really advisable to globally deactivate archiving since some functionality may rely on the behaviour and not work properly afterwars (e.g. SiteService). Technically, you could customize the data model (i.e. contentModel.xml) and add a tag <archive>false</archive> to each type / aspect you don't want archived. If model customization is not an option, you can apply the aspect sys:temporary on nodes during runtime and those also won't be archived.
