C:\Program Files (x86)\Steam\depotcache and steamapps\downloading
What is Steam depotcache? The Steam depotcache folder stores encrypted delta-patch manifest chunks (.depot and .manifest files) used by Steam to verify and assemble game updates. When a game update is interrupted, cancelled, or uninstalled mid-patch, gigabytes of orphaned depot chunks remain locked in C:\Program Files (x86)\Steam\depotcache indefinitely.

Steam saves graphics files for every game you play so levels load faster, and those large files stay behind even after you stop playing or uninstall a game.
