Unable to restore or delete files after running snapshot on Grub

[D3vil0p3r]

I'm using Arch Linux with Zen Kernel and I'm using grub-btrfs + snapper-support package. I performed a test where:
1- I removed neofetch package
2- Created a file hello.txt
3- Removed malcontent package
4- Rebooted
5- Restoring on Grub by selecting the Snapshot related to the PRE-Install of neofetch package.

When I land on the system, effectively I see that I still have neofetch and malcontent packages installed as expected, but I see that hello.txt file still exists and I expected it was deleted since it didn't exist when I installed neofetch package.

Is there a way to manage files on snapshots by grub-btrfs or it works only with pacman packages?

The snapshots you can boot with are always snapshot of the root subvolume (@)
Could it be that you created the hello.txt file on a different subvolume?

I created it in my home folder. It has a different subvolume?

[Schievel1]

It depends on how you setup your machine but most often yes, home is on a different subvolume

Maybe you can test that again and create the file in /hello.txt.

Otherwise what you think is going on here, that restoring subvolumes only restores files installed/ removed by pacman isn't possible. Subvolumes are always restored as a whole and they are not coupled with any program like pacman.
