I have this one folder on my computer that stores pictures and videos. This folder has become so huge (8.2 GB) that my computer started to complain about low memory. I got an external harddrive and, 2 hours of data transfer later, my computer is back to normal! No having to quadruple click on everything, or restarting the computer five times for freezing on boot up! The only down side is that I couldn't tell what system the external harddrive was until I installed it. I wanted NTFS, but got FAT32 instead. Damn. But the computer runs smoothly again!
