Mac Storage Is Full But There Are No Files – How to Fix

If your Mac is showing a “Storage Almost Full” warning, but you can’t find what’s taking up space — don’t worry, you’re not alone. A lot of users see something like100GB used by Applications, but when they check the Applications folder, it only shows 10–15GB worth of apps. Strange, right? This usually happens because of a system bug or leftover hidden files. The good news is, there’s a quick and easy way to fix it — no need to delete anything important or format your Mac. Let’s get into it.

Why Mac Storage Shows as Full Even Though When It’s Not

This issue mostly happens because ofleftover system files,app caches, orfailed app updatesthat macOS doesn’t remove properly. Even if you uninstall an app, some of its hidden files can still stay behind. Over time, they pile up and macOS counts them under the “Applications” section in Storage — even though they’re not real apps anymore.

But here’s where it gets worse. macOS sometimestreats regular files as apps. For example, if you save a screen recording or any large video file inside the Applications folder by mistake (or some app does it automatically), your Mac might think that file is an app. Then, inSettings > Storage, it shows up as if it’s part of your installed applications. In reality, it’s just a file, not an app, and that’s a blunder by macOS.
