I am wondering if there is some way to find out how much disk
space is allotted to a shared object by a client. I want to delete
older data in the shared object as I approach the limit so that the
user is not bothered by pop up settings forms asking them if they
want to increase disk space. It would be a rotating cache of data
where the newest saved data has the highest priority. Is this
possible? I have not found answers anywhere else to this question.
