After checking the file systems, I noticed there is a usage of 60% for /home. and /home only has a very limited of 23GB storage space. On the normal windows I used to own I had more than 800GB of free storage, is there way I can allocate that storage to /home?df result:lsblk:
how to allocate more storage for home directory?
partition
In addition to mkdrive2's answer you may want to consider just creating a new partition and using that for large data.Resizing partitions can be tricky, especially if the /home partition is in physically located between other partitions. It always carries a risk that something might go wrong, so be sure to make a backup before you change partitions with a GParted live distro or similar.
