[Zope] too big data.fs

[Jianping Zhu]

I have redhat 9.0 with zope on it. the size data.fs is 3.2 GB. my
question is
1. how can find to size of folder and file inside data.fs, So i can ask
the idiot who upload large file to zope to delete it.

2, Recentlt i often get troulble of  losing network connection of my
redhat server, is there any relation between the large data.fs and the
disconnetion?

Thanks
