Is system status with a available space of 1.3GB is too low & wat does it mean exactly

it means you have only 1.3 gigabytes of harddrive space left, which limits what you can install on your computer. as you install more software and save more documents the hard-drive space you have left decreases. if it gets more towards 0 you will not be able to save documents or install new software. its at a fine level at the moment.

The short answer is it depends. Please open a terminal and from Applications-> Accessories-> Terminal and type

df -h
sudo fdisk -lu

Please tell... the output of these commands

Thanks

I m previously using windows so i din make changes on the partitions on which i have kept data. Also i wana know can i use these windows partitions 2 install software & also please recommend me the sizes for various partitions in Ubuntu.

As you can see, you (/) root directory is 80% full. Typically I recommend not going over 90% but this may be a little arbitrary.

YES, you can use your windows partitions for installing software. For example, I have created a symbolic link from /usr/local/games which goes to a games folder on a separate partition (my /dev/sda7). In this partition I have Q3A, UT2004, HL, DOOM3, WOP, etc. I also moved my .openarena and .wine folders from home, to this partition - then created a symbolic link back to home.

Using symbolic links is a great way to save space on your ubuntu partition. I have used this keep the size of my home folder small. My large data folders are not kept on home, but rather linked there. For example my Music, Video, Picture folders are all linked to my DATA partition.

As far as partition sizes go. I would recommend a MINIMUM of 10GB for any OS installation. This space should only be used for the allocation a OS specific files. All data should be kept separately on a DATA partition.

Hope this helps

First i thank u 4 ur help. Plz tell me how to create a symbolic link so i can avoid saving my data files in root directory. Ubuntu friends recommended me 2 reinstall as i have assigned more swap area so i have 2 make my installation of Ubuntu better.....thats y i m asking abt Symbolic link
