Hi, I have had a few occasions where I broke an image because I either ran out of disk space or had an endless loop that grew my image endlessly (I think).
But why does Pharo not save the image & .changes file in hidden files named eg ~Pharo.image while it saves? Then it can rename them when saving was successful. Many unix programs do this. (I'm using pharo 6.1 so don't know if newer versions do this) -- Siemen
