I cannot open any file

[nicrnicr]

Dear all,

The memory in my Kubuntu 14.04 has been for a moment to small and since this time, I*cannot open any file. Please could you help me to open them? Nothing happens when I double click and nothing happens when I try to open through a terminal.

By "memory" do you mean drive space (storage) or RAM (memory)?

If your drive is full, you have to un-fill it before you can open any files. Delete some stuff.

If your RAM is full, you have to kill some processes before you can begin another.

Thank you very much oshunluvr for your answer!
I mean the drive space. I failed to save something which was to big. Thereafter I deleted many files and I have now more than 100 GB free.
