	'''A:''' Either delete some file you do not need anymore, or ask for more space (quotum). Generally your quotum will be increased by return, if server disk space allows. However, if you need considerably more than, say 100 Gb, we will ask you request a "project directory" and store the bulk of your files there. See: [[Project Directories]].

	'''A:''' That's a pity. In the worst case, press <~~CTR~~><F2> to get to a text-mode prompt. Log in, and delete some stuff until there is free space. After you logged out, <CTRL><F7> to get back to a graphics mode screen, and perhaps reboot. You should be able to work again.		'''A:''' That's a pity.
