Show size of biggest folders and files in system data 1. Summary

I don't find, how I can view, which folders and files are the biggest in my system data. So I can manually decide which files to delete and which not.



2. Expected behavior

Ideally to have behavior as in SpaceSniffer Windows program.



SpaceSniffer can show sizes of system Windows files.

I can't get similar behavior for Android.



3. Data


ASK Benefit S401
Android 5.1.1
CyanogenMod 12.1 ROM
Rooted


When I install CyanogenMod, system data size — ~700 MB; at the time — ~1,5 GB.

Several hundred megabytes — apps data, for which I would consider the possibility of removal.



4. Not helped

4.1. SpaceSniffer Android alterntaives

All doesn't show system data files and folders.


DiskUsage


DataSize Explorer


Grid Size File Manager




I don't find another DiskUsage alternatives, that can help me.



5. Do not offer


Yes, I understand that operations with system Android files may be risky. I understand that I do actions at my own risk.
Yes, I know about SD card partitioning, and I move all my apps to SD card use Apps2SD.
Yes, I can view system data files, use any file manager, that support root — I use Amaze, — but I don't find file manager, that:


correct sort folders and files in system data
show files/folders size of all files in screen.

Install Solid Explorer and grant it root access. This is the most feature filled file manager that I've tried. Visit the Root (/) partition, click three dots on top right and properties. There you can see a breakdown of the content, file types and top 20 files (it does take a while to index this). 



Alternatively with a terminal emulator use the common Linux tool du and sort by size:

du -ah(x) | sort -n -r | head -n (number_to_show)

I tried to find a build of ncdu for Android which would be ideal but no luck. If you have Ubuntu/Arch/some other system with a package manager installed you could simply apt-get it.
