BEST STORAGE ANALYZER. It's free, open-source, fast, and simple. I've been using it since 2010! Use it to find what's eating up your storage AND if you are rooted, it can help you locate all the hidden pieces of your apps (scan \data) faster than most explorer apps! At this writing, it hasn't been updated since 2017, but it doesn't need to be. It's basically perfect.

Simple, great, tiny app! Been using for years and years. Does exactly what it says. Shows you exactly what is using space graphically without and fluff. App size less than 1mb, so you can install it even when your phone is super full to see what is taking space. No ads! No annoying notifications! No background processes that slow down your phone! I've had one or two devices where the manufacturer configured the file system weird, so you have to click on the right storage device, but that is the fault of the device manufacturers, and really simple bug.

Awesome! No other storage analyzer is so concise and precise. I have tried dozens. Most generate useless fluff requiring an hour of your time to find what this app leads you to in seconds. You do not need pie charts based on categories, tables based on file types, lists based on filesize, bar charts based on user files, system cache, app storage, and junk. Etc. Etc. All you want to know is what takes up space on your phone. This app excels at that with a very slick and *USEFUL* interface.
