I've been tidying up my hard disk recently, as space was getting a little short. I have an SSD drive rather than traditional "spinning rust", and I was down to around 80 GB free. I could of course just buy another drive, or a bigger one, to gain more space. But that would mean re-thinking my backup regime too, in order to ensure that I'd have enough capacity elsewhere to back up all the new stuff.
So it was time for the annual housekeeping session, looking for things I haven't used in ages and which are safe to delete. Installation zip files for printer drivers that are out of date, for example. Or programs that I never use any more, and which can be uninstalled.
If you're short of disk space, there might be other reasons, apart from unused programs and long-forgotten files. Windows often keeps copies of the updates it downloads. And some software packages which have an auto-update feature do the same, as do certain antivirus products. So it can sometimes be difficult to work out where all your disk space has gone.
That's why I like a program called WizTree, which is free (donations accepted but not compulsory) and can be found at http://antibody-software.com/web/software/software/wiztree-finds-the-fil.... It's a small download of around 3 MB and is portable too. It shows you all the folders on your computer, arranged in size order. You can then drill down into each subfolder in order to see what's taking up the space.
And then you can make a sensible decision about whether you can free up that space. You'll probably want to turn off the weird "tree map" when you start the program (that's those coloured blocks at the bottom of the display). Press F9 to do that. Then start exploring the innermost reaches of your PC to look for things you can delete.
WizTree's site is reputable according to Web of Trust, and the installer is malware-free according to VirusTotal.
