With today’s huge hard drives it’s sometimes tough to know where all that room has gone. You buy a one or two terabyte drive, use it for a while and then you’re suddenly running out of storage space. Here’s a solution for you!

Windirstat (available here for free: http://windirstat.info/) gives you a real picture of what your hard drive looks like, in terms of which files are taking up all the room. Download the program and install it. I’ll wait. When you’re done, come back to see how to use the program.

Back? Ok. Here’s what you do:

1. Start Windirstat. This is the menu you will see:

Select the drive that you want to take a look at. Usually that is your C: drive. In my case I have three to choose from but most computers have only one or two drives.

2. WinDirStat will nibble away at your drive, setting up an image for you. As it does this you’ll see little PacMans zipping back and forth. It’s kind of cute, actually. Once all of the stats have been collected, here is what you’ll see:

3. Once WinDirStat has collected the information it needs, it shows you this graphic of your hard drive. It may look confusing at first but it’s really pretty cool. On the top right you’ll have a legend which tells you what color represents each type of file. On mine, the blue represents MPEG-2 files from my DVR. Each little section of that blue area is an individual file while the whole blue area on the left is a folder. Each color group represents a folder, each smaller highlighted area is an individual file.

4. Looking at this graphic, you’ll be able to see what files and folders are taking up the most room. If you click on each file, WinDirStat immediately shows you what file it is up on the top left section. If there is one particularly huge file, you can then decide if it’s something you want to save or archive or delete.

5. Some areas that WindDirStat will show you are obviously off limits for deletion. Any of the Windows files, for instance, must be left alone. There are two yellow files on the lower right, as an example, which represent two important Windows files; the pagefil.sys and the hiberfil.sys. These are your ‘scratch pad’ files and are about the same size as the amount of RAM in your system. Don’t touch them.

6. Once you’ve spent some time finding the files and folders that are taking up extra space, delete them or archive them to a DVD. Then you can reload WinDirStat and see what the big picture looks like. I keep pretty good track of what’s on my drives but there are always some files that seem to crop up that I could delete. See what you can find on your drive.
