I confirm the problem, also with WinRAR and 7zip. Somehow the files:
web2py\applications\examples\static\epydoc\web2py.gluon.sqlhtml.ExporterTSV-class.html web2py\applications\examples\static\epydoc\web2py.gluon.sqlhtml.ExporterHtml-class.html web2py\applications\examples\static\epydoc\web2py.gluon.sqlhtml.ExporterCsv-class.html are present two times in the zip files. The problem is present in 2.0.9 stable and night thrunk, but is already resolved in the trunk ;-) Nico --
