That old adage, "work expands to fill the time available for it," often comes to mind as I use modern storage devices. Like a 1TB hard drive. "Files expand to fill the space available for them." It seems almost like a foggy dream now, but not that long ago it was cutting edge to have a hard drive in the 200MB range. And it really wasn't that long ago that floppy diskettes--which held a whopping 1.44MB--were the norm for saving/sharing files. Now? Each photograph I take with my DSLR cameras is too big to fit on one of those old floppies! I'm backing up files onto disks measured in terabytes. TERABYTES!! Amazing. And I don't know about anyone else, but for me there's just no end in sight. I keep using more and more space, and keep expecting storage options to keep pace.
