Trash X for Mac

From Northern Softworks:

Trash X is a fully functional trashcan for Mac OS X. Extremely simple to use, it functions just like the classic Mac OS Trashcan - files and folders dropped on it are moved to the trash, and disks droppped on it are ejected. In addition, it also features numerous functions for the power user:

• Instantly delete files and folders without sending them to the trash
• Empty trash only on selected disks
• Securely Delete (Shred) files and folders
• Securely Delete (Shred) trash only on selected disks
• Securely Overwrite (Shred) available free space on disks
• Empty Classic Mac OS Trashes
• Empty Trashes as root
• Execute OS X system maintenance scripts

And of course, you can use it just like the trashcan you've always had on your desktop. Trash X is completely safe and it requires no system hacks or Terminal command line voodoo. Place an alias or copy of it on your desktop, in your documents folder, or anywhere else you wish. COOL TIP: Put Trash X in your Finder windows toolbar to have easy access to it in any folder.
