l had a openoffice 'text' file which was used for a diary. it got to 100MB and refused to open. luckily got an older version of it ~87MB which can be opened, l am splitting up diary to reduce its size, decided, use open office just for text for now on and if photos I either use notes app, google docs or yahoo email for those ''days. I prefer notes, as it easily accepts photos, needs no internet, can export as pdf, Question is, will it become unstable and refuse to open if it gets above 100MB. my 5GB of icloud has all been used up, but does that matter?
