Size matters

See the size of all your files and folders with this free tree view utility.

With Windows, it can be hard to see the trees for the forest; it does a pretty good job with the "big picture," but you've got to do some clicking to see the details, which actually makes it harder to get an accurate overview of your system. JAM's TreeSize Free is a nifty bit of freeware that displays the size of every folder and file, including every subfolder, in a series of expandable Explorer-like tree views. You can use TreeSize Free as a standalone app activated from the desktop or start menu, but you can also associate it with the Windows context menu for right-click access.

TreeSize Free's compact interface opened with a blank main view, which we quickly populated by clicking Scan on the menu bar and selecting a drive. TreeSize Free doesn't merely rearrange system information for added convenience (not that there's anything wrong with that) but instead scans your disks and directories, displaying progress via graphs and various icons. Scanning our drive took a few minutes but less time than comparable processes, such as indexing for searching. We clicked Options and selected the check box to show TreeSize Free in context menus. When the program finished its scan, we closed it and then opened Explorer. We browsed to a random folder on our C drive and right-clicked it. TreeSize Free was listed in the context menu. We clicked it, and the program opened with the selected directory displayed. We clicked Expand on the program's menu bar and selected each of the six Levels, each of which opened the successive directory layer in its main view, with file and folder sizes displayed as figures and bar graphs. It was easy to switch between levels as well as views for size, percent, allocated space, file count, compression rate, sorting, and more. Pausing the cursor over any item in the view called up a detailed view of the item's attributes, a helpful touch.

TreeSize Free is the sort of freeware we like a lot, something that adds a really useful feature that's unobtrusive when you don't need it and a right-click away when you do. It's great for getting an accurate view of just where all the trees are in your forest.
