Your computer’s hard drive is like a refrigerator; no matter how big it is, you’ll eventually fill it up.
And just like your refrigerator, getting rid of unneeded items is much cheaper than buying a bigger one.
The problem for most of you is that you don’t know what’s hogging up all the space, so you don’t really know what to get rid of.
In general, uninstalling old programs that you no longer use is a good start, but if you have lots of video or music that you no longer care about, those are space hogs too.
If you’re a Windows user, you can get a lot of help from a free program called TreeSize.
In Windows, the directory structure is referred to as a tree and each folder is like a branch. TreeSize will show you how large each folder is so you have a better idea where the space hogs reside.
A Word of Caution: You should never delete anything if you don’t know what it is and always make sure you have a verified backup before attempting to clean up your hard drive.
