[d3f4ult]

Hello Kali Linux Forum!

I have a Problem with my Hard Disk in Kali Linux.
I was normally using Kali Linux installed on my Hard Disk withouth dual boot & went to the gym after starting qbitorrent to download a torrent.
When i went back to my Computer i saw a Notification stating "Your ./var is full" or something like that. I went checking for other disk space's and now my hard disk look's like this.Screenshot from 2017-08-21 12-21-15.jpg

How can i give them more Disk Space? Because i have a 1TB hard disk and i have:

Size: 25 GB — 15 GB free (40.3% full)
Device: /dev/d3f4ult-vg/root
Contents: Ext4 (version 1.0) — Mounted at Filesystem Root

You should be able to use gparted to allocate more disk by resizing the partitions.

That's why i prefer All files in one partition during kali-linux installation.

Use gparted to extend space.

Run sudo apt autoremove && sudo apt autoclean to gain some more space.
