I'm very new in the Ubuntu family (I downloaded Ubuntu 12.04 LTS , just 2 days ago, I must learn Linux for college).

Second of all, English is not my native language, but I'll try to be as clear as possible).

I installed Ubuntu on a 1 GB flash drive using Universal USB Installer, following the instructions on the It worked just fine.

So i started using the Terminal, to learn about commands, and I edited a text file, a few times, and after a few hours when I tried to save the text file again it displayed me the " low disk space .." message.

I think it also stored the Firefox history/cache.

Anyway, my question is, how can I clear the space?

Side note: while using Universal Usb, it asked me for the size of persistent folders ( or something like that) and i specified 200 MB, thinking that this is for file storage. Have I done good? Or wrong?

  1. I recommend you use at least 2GB or even larger USB stick (1 or 2 GB for persistence) in order to avoid such space problems, and install a program like Bleachbit to clean cache, etc. from time to time.
  2. As a temporary solution to the problem with your present USB drive, you can try and delete the contents of a number of your (hidden) folders (which you can see when you press Ctrl+H in Nautilus) in your home folder such as: .cache, .thumbnails, .mozilla, etc.

But use Bleachbit with caution and check/uncheck items only after fully understanding what they mean. – user25656 Jan 29 '13 at 9:40
