I write up a daily update on openoffice .odt, I tried to save it other day, but it said there was insufficient space. Indeed available space had gone down from ~26GB down to ~49kB, after keeping my mbpr on for ~ couple of hours? I don't understand why there is a drain on my HD space, as now there is 10% free available space in my 250GB SSD HD. either way, l can't seem to find my .odt file anymore. it is no longer recoverable. could it be hiding somewhere that I can't find? and good idea to prevent it in future when available space is running real low, is to save it to my external HD?
