Are there any size limitations on fit files?

Hello! I'm developing an app for a 920XT and was wondering if I should be concerned about any possible size limitations for the fit files the application is generating. From my estimates, it seems to produce 200KB of data per hour, and I was worried about users who are running the application for a long period of time. What would happen on the device if the system is running low on space? From what I have gathered so far, it seems to overwrite older files, but is there any sort of hard limit to the file size?
