Hi, the Boost.Filesystem documentation at e.g.: http://www.boost.org/doc/libs/1_40_0/libs/filesystem/doc/reference.html#Oper... seems to refer to more recent version. As a specific example, there are no overloads of remove in 1.40 that accepts an instance of boost::system::error_code (as opposed to what the documentation indicates) - easily verifiable in e.g.: http://svn.boost.org/svn/boost/tags/release/Boost_1_40_0/boost/filesystem/op... Is the actual 1.40 documentation available online somewhere? / Johan
