There are several ways you can add references and files to your Mendeley library:
Add papers to Mendeley by dragging and dropping a PDF into the Mendeley Reference Manager window. Mendeley will automatically extract the details from the document and create a library entry.
You can also drag and drop a folder containing multiple papers - Mendeley will work its way through the contents, creating library entries for the PDFs it finds.
Use the 'Add' Button
Use the 'Add' button if the top left menu bar to add individual files or a folder of files. You can also add

You may have to enter citation information manually, search the Mendeley catalog, or enter the DOI, PMID, or ArcXiv ID under Catalog IDs and use the Lookup (magnifying glass).
