How to clean up and regain some hard disk space

Recently I realized that my three (3) year old machine is running slowly. Every time I launch an application, it would take at least a minute for it to load up.

Checking through the available space on my hard disk, I see that only 2.5 GB out of 74.4 GB space is available. This must be the reason why my machine is running slowly. Ever since I started using the machine, it has not been cleaned up in anyway. Short to say, everything goes in, nothing comes out!

At the same time, I also needed some space to install a database to work on some programming assignment. Since the size of the database is at least 10 GB, I need to clean up and regain enough hard disk space to be able to start work. Otherwise, I’m stuck as I can’t go screaming to my boss.. I need a new server with big hard disk capacity! Times are bad and I’m sure my boss won’t spend money on a new server just like that.

With this challenge, the only thing I could do is to delete unwanted files and backup the necessary ones to an external HDD. This task itself is a challenge because I do not know where the big files are. Imagine 3 years of data sitting deep inside folders. How would I know which folder holds to the big files?

Then I remember a tool by the name of SC-DiskInfo introduced by a SQL Server instructor many years ago. The good thing about this tool, it displays your machine’s disk space usage and shows which folders take up the most space. So yes, you will be able to easily spot the folder which takes up the most space.

Running the tool, I can easily drill down deeply into folders which were taking up most of the space. From the screenshot above, obviously most of the big files are residing in the Desktop folder. Drilling in, I found some sub folders storing some music and video files which I have forgotten that the files even exist. All these while, those big files were sitting in there clogging up and slowing the machine down without me realizing it. Shucks, I should have ran this tool much earlier.

So from just 2.45 GB, I managed to regain some hdd space to about 21.5 GB.

Next, I ran the Windows XP Disk Cleanup utility. From there, I also managed to get another 17 GB! See the screenshot below:

You will be surprise to see how hugh the temporary files are on your machine. Just a note that the clean up process can take quite a while. Mine took at least 3 hours to run.

Anyway, I’m happy now that my machine performs better and faster. For those of you needing to clean up and regain some hard disk space, give SC-DiskInfo and Windows XP Disk Cleanup a try now and do let me know how much space you’ve regained.
