Years ago, I was proud to own an 80MHz, 16MB RAM PC with a huge 512MB harddisk. But even on this incredibly huge harddisk, my diskspace seemed to disappear over time. So I wrote a little tool to find out where all my diskspace had gone: I called it gettree, as it showed all files in a directory and also calculated the size of subtrees. Over the years, the OS I used changed, but the problem stayed. Using Linux, there are some tools to deal with it, but I couldn’t find anything that was clearly laid out, intuitive to browse, and doesn’t need X-Windows.
