<archive>false</archive> This means that files that has been deleted will end up in "Alfresco trashcan" but if I want to enable this features but I want to exclude some file, example some temporarly files that´s been created by MS Office, word and excel. These files I don´t need to be archived.
Look at WEB-INF/classes/alfresco/model-specific-services-context.xml. The bean tempFileMarkerInterceptor defines patterns for files that are given the sys:temporary aspect. Anything with this aspect will not be archived.
