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.

Exceptional app! I was absolutely thrilled to be able to isolate where storage space was being used on my Samsung S8+ internal memory and able to recover many gigabytes of space by removing or moving files around. It may not sound like much but I went from 1.2 to 7.5 GB in less than 24 hours. Funny little thing though is that it's names my internal memory as "Storage Card" but once I got used to that and how to use the app, it was very informative. Please don't upgrade. Great as is.

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.
