Folder Size is a freemiumdisk space analyzer for Windows written by MindGems Inc. The product uses a Windows Explorer-like interface that can show data as a pie chart or a bar graph. According to PCWorld.com, as of September 2, 2010, the product was a little more cumbersome than necessary but overall was considered to have an edge over Space Sniffer (a freeware alternative) because it had additional functionality and provided more information.[1]CNET observed that the program is basic but noted that this is generally what is required of such programs.[2] In the free version, the user can delete files; paid versions add the ability to copy, transfer, etc.[3]
