Papers is one of them.

It’s just the best software to organize you collection of scientific papers. Can retrieve new ones with the API to query PubMed or Google Scholar, automatically download the PDF (and, cool,.. supports proxy so that you can use your library subscription even when at home), grab all data to organize the database, has a spotlight search box, and Previews your PDFs…

Just too cool, and with a small price for PhD students 🙂

You can see where  you are at a glance, you can click on upper folders and go to them, and also drag and drop files to upper folders to copy/move them.

Alternatively you can enable the “path” view in the title: see this tip.
