FFx takes up too much of the Downloads Folder. When I ask for it to be "Moved to Trash", I am told this can't be done "because it is open. Please send me exact instructions as to what I must do to delete FFx completely. It is stopping me from downloading other useful programmes, as with FFX there, the computer says, "cannot download as there is not enough space for this new programme". Thank you. I now know these messages must not exceed 5 KB.
