Disk space decreasing for no reason

Hello world, I have a question, why does the disk space is constantly decreasing on it’s own for no reasons on Fedora 40?

I already had the same problematic in the past with a previous version of Fedora that I uninstalled for this very same problem because I had no more disk space available and I could do nothing about it.

Can someone help ? I am not really comfortable with the Linux environment but I could tweak with commands on the terminal and I do want to stay and keep this version of Fedora…

I just realized that the information given by the numbers appearing next to the " folders UI " and the pre installed app Disk Usage Analyzer are not the same.

What version of Fedora, did you do a standard install?

What amount are you talking of, over which time, how much?

Is the available space decreasing or does it fill up?

This might be a filesystem issue, or you may have a program writing too many logs or somethint.

What version of Fedora, did you do a standard install?

Fedora 40, installed yesterday alongside windows 11 on a laptop with standard and automatic install for dual boot.

What amount are you talking of, over which time, how much?

After creating this topic I already lost 100Mb, when I installed BleachBit I lost something like 4GB.

Is the available space decreasing or does it fill up?

I don’t know for sure, I mean the numbers next to the disk available space in the folder menu are decreasing, but I don’t know what is really going on.

While writing this message 100Mb less on the Fedora Linux main folder.

I don’t know how disk space checkers check, but I suspect:

  • Log data (although I’d think most of that would be on /var on tmpfs?)
  • Snapshot/recovery/CoW back-up data being created
  • Search indexing (tracker3 GNOME)

In a terminal you can look at:
df -hT
or if you’re using btrfs
sudo btrfs filesystem usage /

There are also graphical tools available:
gnome-system-monitor has a file system tab where you can look at usage.
sudo dnf install gnome-system-monitor
disk-usage-analyzer (baobab) is also available
sudo dnf install baobab
