GMass runs on a farm of Windows servers, and as the chief systems administrator, one of the constant worries in the back of my mind is whether any of the disks on any of the servers is near capacity. Naturally, I decided to Google "Windows disk space monitor".

Given the usefulness of such a tool for any Windows server administrator like myself, I was expecting to be overwhelmed with viable options. Not only was I not overwhelmed, but the first two disk space monitors I downloaded sucked - to the point that I can't even believe they are on the first page of Google. It goes to show that Google's search results don't always yield the best tools, just the most popular. Case in point, GMass is probably the world's best Gmail mail merge tool, but a search for "Gmail mail merge" and GMass is shown near the bottom of page 1 and sometimes at the top of page 2. Yes, competition for that term is stiff indeed.
