windirstat VS btdu

something that helps me is If you want to reformat, Winderstat scans your drive and shows you the size of every folder, plus a visual representation so you see whats taking up more space exactly

Not xcom specific advice, but this tool is pretty nifty: https://windirstat.net/

just install https://windirstat.net and search for a big clusters of files

There's a utility called WinDirStat that can visualize the storage on your drive to make tracking down large files easier.

Download WinDirStat

Delete some things to get a bit of space, then download windirstat. This application scans your drive and provides a nice way to see your whole drive and what's taking up the most space. You can manually click on each colored area and delete entire directories instead of trying to hunt down whats taking up space.

I'm using WinDirStat for a long time

A good free utility for checking disk space is 'WinDirStat'

Hello. I have a 2 TB nvme mounted as a subvol that contains dockervols. I recently noticed this discrepancy df -h | grep nvme0n1p1 /dev/nvme0n1p1 1.9T 1.3T 569G 70% /data vs. sudo du -h -d 0 /data 1.1T /data I tried using the btdu tool but I am not sure if I had it installed correctly as it didn't show the output like the examples shown on the github (https://github.com/CyberShadow/btdu)

btdu fastest and easiest tool to analyze space usage in compressed btrfs with lots of snapshots (especially in expert mode)

It doesn't seem BTRFS's fault. You could run btdu on your subvolumes to understand what's going on.

However, honestly, the best way to get a quick overview of where all your space is being used is btdu.

If you want to diagnose where you think there may be space used up that you don't quite understand, then btrfs fi du and third party tools btdu and compsize are useful.

And btdu to get an overall impressions of where space is being used if the above isn't useful enough.
