My arch system has 190GB total disk space. I have installed filelight. Recently I deleted the virtual windows 10 in my arch. The windows 10 is about 40GB. I checked the available space by the command "df -h" and it still shows the same available space as before, which is about 80GB. However when I used filelight, it showed about 140GB available after summing up the scanning result from root folder and home folder. I searched online about "deleting files in Linux and the space is not released" but I didn't find useful information for my situation. Now I'm not sure whether filelight or df -h is correct. "Dolphin" shows the same free space as df -h. And filelight just shows the used space of root folder and home folder respectively. I manually added them and subtracted it from 190G. And how can I make the available space right?

Are you using btrfs?

Yes, btrfs.

btrfs filesystem usage /mountpointDo you use snapshots?

Yes, I used snapshot that can only apply to btrfs, not the older type of snapshot. ( I forgot the name)

So you'll have to make sure the file you deleted doesn't exist in any snapshot, otherwise the space isn't freed.
Does the command I gave you tell you more about the discrepancy you're observing?

I used the command and it agreed with df -h.

I deleted all my previous snapshots, and it is normal now (with much more extra free space), except for that the filelight shows less free space than that of df -h now. And since very long time ago, I can't delete one exact snapshot. I don't know why. But never mind.
