What's in your Downloads folder?
Pick a folder. Your browser counts its files by type, size and age, on your Mac. Nothing is uploaded, and no file is opened.
or drag a folder here, Downloads or Desktop straight from the Finder sidebar
Tip: in the dialog, press ⌥⌘L to jump to Downloads, or ⇧⌘D for the Desktop. Chrome will ask to "upload" the files: nothing leaves your Mac, they are only counted in this tab.
It reads a folder on your computer, so it only works on a Mac.

Free on the Mac App Store. One Undo puts every file back.
How it works
Your browser lists the files at the top level of the folder you pick: their name, size and last modified date. It never opens a file and sends nothing to a server; close the tab and it's gone. Folders inside the folder are counted but left alone, the way Declutr leaves them in place.
Each file goes into the category Declutr would put it in, by its extension. The table below is the app's own list (Declutr 4.2). Files with an extension that isn't listed go to Other.
