You can see that on my MacBook Air, this folder contains a bunch of “.bts” files—which are tiny “aliases” to the original files stored elsewhere.

Now here’s what’s great—If I need an installer locally, I just double-click it, and it downloads in place! And when I’m finished with installer, I simply delete it in the Finder, and shortly thereafter I’ll see its “.bts” alias re-appear.

Huge BTSync fan here.
