Where OS X gets unique with handling files set for deletion is with additional storage mediums such as external hard drives and USB thumb drives. This is pretty common file handling across most operating systems.Įach storage device that you plug into a Mac running OS X gets its own Trash Can specific to that device. When you delete a file in OS X (that is, empty the Trash Can) the operating system is not actually erasing the data (unless you tell it to, more on that in a bit), but rather it is actually just marking the space that said file took up on the physical hard drive as free space to be written over with new data.

I hope this extensive rundown of the Trash Can will help you better understand and manage your files and storage space on your Mac. Even I was thrown for a loop or two when I made the jump to OS X. However, the Trash Can, and even deleting files in general, both work very differently in OS X than other operating systems. Admittedly at first glance, an article on how to use and understand the Trash Can inside of OS X may seem a bit beneath even the most novice of newcomers.
