- It says I have 286.6 GB total space, of which only 60.8 GB is used, leaving 225.9 GB available. That being the case, why does it say 100% usage in the list of directories?
You have obviously chosen to scan your home directory. What is shown is what folders make up the total of the home directory, and hence all the contents of the home directory will add up to 100%. As a clarification, it is shown that the home directory contains 100% of the listed directories and files.
- Storage is on a separate partition, with a symlinked directory in my home folder. Why is it being included in the total? (It isn't more than 1/3 full in any case).
This might indeed make it a bit hard to interpret the figures. What I do know is that the program will follow symlinks. As to my knowledge, this can't be disabled.
I am not sure from where the program will get the "Total filesystem capacity" data at the top when several filesystems are in play on the scanned path through symlinks.
For a clearer view on the file system capacity (capacities), it might be more useful to use the
df terminal command. Run with an option,
df -hto get human readable file sizes. The command will list the physical drives and the mount points, e.g.:
$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda5 158G 51G 99G 34% /
none 4,0K 0 4,0K 0% /sys/fs/cgroup
udev 1,9G 4,0K 1,9G 1% /dev
tmpfs 386M 1,2M 385M 1% /run
none 5,0M 0 5,0M 0% /run/lock
none 1,9G 1,5M 1,9G 1% /run/shm
none 100M 60K 100M 1% /run/user
deskt:/media/Samsung 801G 414G 388G 52% /mnt/deskt/data
deskt:/home/carl 113G 40G 68G 37% /mnt/deskt/carl
deskt:/tmp 113G 40G 68G 37% /mnt/deskt/tmp
/dev/sda3 63G 26G 37G 42% /media/carl/OS
/dev/sda? entries will show the capacity and usage of the different partitions.
On a side note, a more natural approach of having the home folder on a separate partition would be to mount /home/ to that partition, rather than doing it with a symlink.
