For my ubuntu usb distribution I bought an 8GB key
and set up 4GB as reserved extra space but during update
process ubuntu warned:
not enough space, please use 'clean' command to
free up memory.
(issue 1)
I followed the advice and used the command:
'sudo apt-get clean' to free up memory but I wonder
where temporary and old files are(I mean which folders
contain them)and which commands to use to delete them,
in order to free up more memory.
(issue 2)
I also followed the advice issuing to use 'Disk Usage
Analyzer' but I don't know how data is organized.
Where can I find a table or and explanation about
the content of all folders of ubuntu file system?
(issue 3)
Then I also decided to investigate how space is used.
I opened my ubuntu usb key on ubuntu CD session, so I
found my original system in casper folder(700 MB) +
'casper-rw' file(2.9 GB) in main usb folder containing
probably all updates.
I ask for confirmation about this.
(issue 4)
When I built my usb distribution I chose the option to
set up a reserved extra space for settings and documents,
but when I run my usb ubuntu I cannot access them as
a partition, however I can access my 'home' folder
from launcher, but as I cannot access my reserved extra
space as a partition I don't know which settings are
saved.
As my 'casper-rw' file is about 2.9 GB I suspect
that it represents my reserved extra space file(maybe
this extra space is fully contained in a unique file),
so containing all settings, updates and home folder.
Or maybe updates are not counted as reserved extra
space but still contained in file casper-rw.
Which is the truth? Which folders I find in
'Disk Usage Analyzer' are contained in my reserved
extra space?
Can anyone please address this issue?
