How do I know the persistent file size for storing changes of a bootable USB stick? I need to know: A) the space given to persistent storage B) how much of it is free.

My idea is to copy some of my files into the usb drive until it gets full. I am asking this question in order to know when to stop.

I created it using Pen Drive Linux's USB Installer and following this instructions.

Thanks in advance!

No one? Please, I need to know this. – pablofiumara Oct 29 '13 at 20:40

Open a terminal (Ctrl + Alt + T) and type the following command:

df . -h

Output can look like:

Filesystem            Size  Used Avail Use% Mounted on
/cow                   14G   74M   13G   1% /

And in case you like to change the size of the persistent file you can take a look at:

Have Fun

Thanks for your answer. Unfortunately, that does not solve my question. I tried running the command you told and the output only shows hard drives (not usb flash drives). – pablofiumara Nov 12 '14 at 8:32
