You'll get the same answer here as in the C NG ;) The portable way to check for this is to try to open the file (you may use ifstream, or fopen as in C) to check if it succeeds, then close it immediately. Two main issues are: - various operating systems may have various restrictions on visibility or accessibility of files within a given storage/directory. - on a multitasking OS, a file that exists at a given time may be deleted by the next statement. So in general, best is to just try to use the file, and report the error at that point. hth-Ivan -- http://ivan.vecerina.com/contact/?subject=NG_POST <- email contact form Brainbench MVP for C++ <> http://www.brainbench.com Back to top Bruintje Beer Guest Posted: Sun Jul 30, 2006 9:11 am    Post subject: Re: Check whether a file exists "sword" <solitudesword (AT) gmail (DOT) com> schreef in bericht news:1154241363.816998.8750 (AT) m73g2000cwd (DOT) googlegroups.com...
