Trash
From WikiMac, Everyone's Mac Knowledgebase
The Trash or Wastebasket is a holding place for deleted items before they are finally removed from the Macintosh.
[edit] Location of the Trash
The Trash appears on the desktop, and its very appearance there would make users assume that this was the only place with a Trash.
In reality, there is another Trash folder -- this time invisible -- on the root of the startup drive -- named Trash. This one, however, can only be seen if you're viewing your Mac across the network. As of Mac OS X, this name has shifted over to 501.
[edit] Bulge or No Bulge?
In System 1, the Trash did not bulge -- even with items in the Trash! (You had to double-click the Trash to see if anything was in it.) It took at least System 6, but verifiably at least until System 7, for this to be solved.
