We’ve shown you lots of ways to free up hard drive space before, but before you go and download disk-visualising programs, you might want to do a quick search for big files. Here’s how to do it on Windows and OS X.
If you have lots of time, you could go rummaging around your drives in Explorer (or the command-line if getting nothing else done in the next few years doesn’t bother you) in an effort to reclaim space. Alternatively, you could do what the rest of us do and fire up WinDirStat or SequoiaView, which display the files and folders of your hard drives as coloured blocks of various sizes. With these visualisation tools, it’s easy to identify where your space is going.
