diskspace

[Zahid Rahman]

Hi,

*Can you please explain something that has always confused me about free
space.*

*I have a usb with the linux operating system on it.*

*So I know  I have 57.3 GB free space on my usb /dev/sdb.*
sudo  fdisk -l says :
Disk /dev/sdb: 57.31 GiB, 61530439680 bytes, 120176640 sectors
Disk model: Ultra
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x2259da88



*if I select /home directory in the file manager it say  *
*1 item, Free space 3.8 GB .*

*When I select /home directory should it not say*

*  1 item 57.3 Free space ?*

*if select I   /home/Download it still says*

* free space 3.8 GB *
*again I expect to see 57.3 free space.*

*what is this figure of 3.8 GB mean and how can I change it ?*

* the output saying here  with a listing of directories and used and free
space of e.g.  3.9 GB /dev*
