a folder size exploration tool

I often want to check what is contributing to the size of a folder.

While there are great tools like DaisyDisk and WinDirStat, I wanted something I wouldn't have to install or get approved.

I found that, at least in Chromium based browsers, there exists the showDirectoryPicker api. Which lets me check all the files and sizes in a folder.

So I got to work, and first made a circular view, that let's you navigate through the folders, and shows the folder's content's sizes. The arcs are drawn with svg path elements. And the hovering is synchronized with preact context. I also made a little icon for the folders.

I then also went ahead, and made a TreeMap view. It isn't fancy, but should still give you an overview. It doesn't do really smart ordering/splitting, but at least tries to keep the rectangles as square as possible, when deciding how to split.

You can switch between the views with the button in the top right. The icons there are handwritten svg path d command :D
