Often file names are very long.
It would be useful and mitigate potential corruption of EndNote libraries if files for which meta-data is available could be renamed according to a schema, e.g. Year_Surname_Title.pdf, so that Year might be replaced by year of publication e.g. 2002, Surname by the surname of the first Author e.g. Van-Hout and Title by a shortened version of the title containing only alphanumeric characters e.g. A paper on typographic markings.
