Why doesn't Windows Explorer show folder sizes in the list?

Because a folder’s size is the sum of everything inside it, and computing that for every folder in a list would mean scanning every folder tree before the screen could even draw. Windows avoids that cost by leaving the Size column blank for folders and offering the Properties dialog for the one folder you ask about. Elegant File Explorer still gives you that recursive total in Properties, plus a Folder statistics panel that breaks the folder down by file type.

How do I see the real, total size of a folder including subfolders?

Right-click the folder and open Properties. It walks the entire folder tree in the background — every file and subfolder, all the way down — and shows the total size along with the file and folder counts. It says “Calculating…” while it works and doesn’t follow links or junctions, so the number reflects what actually lives in that folder.

What's the difference between Properties and Folder statistics?

Properties gives you the total recursive size of one folder (subfolders included). Folder statistics gives you a breakdown by file type of the folder you’re currently looking at — two bar charts, one ranking types by total size and one by how many files there are. Properties answers “how big is this whole folder?”; statistics answers “what’s taking up the room in here?”.

Does Folder statistics count the files inside subfolders?

No — it summarizes the items in the current listing (the folder you have open), grouped by type. It doesn’t descend into subfolders to add their contents. For the full recursive weight of a folder that has nested subfolders, use Properties, which is the recursive tool.

Can I compare several folders' sizes at once?

Select the folders and open Selection details for a quick per-item summary with a combined total, or open each in Properties for the exact recursive number. For files (not folders), sorting the Size column biggest-first in Details view surfaces the heavy ones instantly. Available now on the Microsoft Store.

Open any folder in Windows Explorer, switch to Details view, and look at the Size column. For files, it’s filled in. For folders, it’s blank — every single one. That empty column is one of the oldest quiet frustrations of using Windows: the one thing you most want to know, how big is this folder, is exactly the thing the list refuses to tell you.

So you do the workaround everyone does: right-click a folder, choose Properties, wait for the little counter to spin, read the number, close the window. Then repeat for the next folder. And the next. To compare five folders you open five dialogs, one at a time, jotting the numbers in your head. It works, but it’s slow, and it never gives you the one thing you actually came for: a side-by-side picture of where the space went.

This guide is about getting that picture — the real size of a folder, and, better still, a breakdown of what’s inside it — without the one-dialog-at-a-time grind.

Why the Size column is blank for folders#

It’s not an oversight, exactly. A file has a size the moment you look at it — the number is right there in the file system. A folder doesn’t: its “size” is the sum of everything inside it, including every subfolder, all the way down. To show that number in a list of a hundred folders, Windows would have to walk every one of those trees before it could draw the screen — and on a big drive that could take a while. So Explorer takes the safe route and leaves the column blank, handing you the Properties dialog for the one folder you ask about.

That’s a reasonable trade-off for Windows. It’s just not much help when the whole point is to scan your folders and spot the heavy one.

The real size of one folder, calculated in the background#

Elegant File Explorer keeps the familiar answer where you’d expect it. Right-click a folder, open Properties, and it does the honest, recursive thing: it walks the entire folder tree in the background — every file, every subfolder, all the way down — adding up the bytes and counting the files and folders as it goes. While it works it shows “Calculating…”, then settles on the final number: total size, file count, folder count.

A couple of details worth knowing, because they’re the difference between a number you can trust and one you can’t:

It’s truly recursive — the total includes the contents of every subfolder, not just the files sitting at the top level. That’s the number you want when a folder has a deep structure.
It doesn’t follow reparse points (links and junctions), so a symbolic link pointing elsewhere on the disk isn’t counted twice or sent chasing across your drive. The total reflects what actually lives in that folder.
If you close the window before it finishes, the scan stops — it won’t keep grinding in the background for a dialog you’ve dismissed.

Properties also shows the created, modified and accessed dates, the file attributes as small chips (Read-only, Hidden, System, and so on), and, for files that came from the web, the download’s origin. But the headline, for our purposes, is that recursive total — the honest weight of the folder.

The better view: what’s actually eating the space#

Knowing a folder weighs 12 GB is useful. Knowing that 9 of those gigabytes are video files is what actually lets you act. That’s where the Folder statistics panel comes in, and it’s the part Explorer has no answer for at all.

Open a folder, then choose Folder statistics (it’s on the menu, and also in the command palette under Ctrl+P). A panel opens with a plain-language header — “N files · N folders · total size” — and, below it, two horizontal bar charts side by side:

By size — top 10: your file types ranked by how many bytes each type takes up. This is the one that names the culprit. If PDFs, or videos, or raw photos are quietly hogging the folder, they rise to the top of this chart with their total size spelled out beside the bar.
By count — top 10: the same file types, but ranked by how many files there are. This tells a different story — the type you have the most of, which isn’t always the type taking the most room. A thousand tiny text files can top the count chart while barely registering on the size one.

Each bar is drawn in one of a handful of cycling colours with its value written right next to it, so the whole shape of the folder — what’s big, what’s plentiful — reads at a glance. If the folder has no files at all, the panel just says so instead of drawing empty charts.

There’s one honest limitation to know, and it pairs neatly with Properties above. Folder statistics summarizes the folder you’re actually looking at — the files listed in front of you — not the full recursive tree. It groups the items in the current listing by type; it doesn’t descend into subfolders to add their contents. So the two tools split the job cleanly:

Want the total weight of a folder that has lots of nested subfolders? Use Properties — it’s the recursive one.
Want to see which types are eating the folder you’re standing in? Use Folder statistics — it’s the instant breakdown.

Used together, you go from “this folder is huge” to “this folder is huge because of these ten video files” in about two clicks.

A quick way to weigh several folders at once#

If what you really want is to compare a handful of folders — which of my project folders is the fat one? — there’s a lighter path too. Select several items and open Selection details: you get a card per item, and a subtitle that sums the selection up (“N items · X files, Y folders · total size”). It’s a fast way to total up a specific pile of things you’ve hand-picked, without opening Properties five times.

And of course, the plain Size column is always there in Details view for the files themselves — sort by it, biggest first, and the heavy files float straight to the top of whatever folder you’re in.

Seeing the size isn’t the same as freeing it#

One thing this guide deliberately doesn’t do is delete anything. Folder statistics and Properties are about understanding where your space went — reading the map before you touch the terrain. That’s on purpose: seeing the numbers calmly, before you act, is what keeps a cleanup from turning into an accident.

When you’ve found the heavy folder and you’re ready to actually reclaim the space — hunt down the giant files, set aside old installers, clear out duplicate copies — that’s a separate, careful process, and we wrote it up in free up disk space without deleting anything important. Think of this post as the diagnosis and that one as the treatment: first you see the sizes, then you decide, and only then do you free the space.
