Recover cells

Hi, my question is Does Toon Boom Harmony store cells in some cache or file while you are working on a project? are they stored in .xstage, or .xstagetilde?, I increased the exposure of a cell by about 25, then couldn’t undo the action because of the limit of undo operations,

I’m wondering if there will be a file containing the cells i lost

thanks.
