I know there must be a simple function or something in C++ to delete files from disk but I cannot find it in the msdn because other than delete I just dont know what keyword to search for (and delete just brings up info on new/delete). If anyone could point me in the right direction Id be very grateful. p.s. Its an mfc sdi app- don''t know whether that is relevant.

hmm... try remove("C:\\YourFile");

I forgot which one to include.

Thanks very much that should do nicely

For a more standard, cross-platform solution, use unlink(). It works under UNIX as well as DOS/Windows, and probably on other platforms as well.

Under true multiuser systems such as UNIX, a file may possess hard and soft links to itself. Unlink therefore removes one of these links, and when there is only one link left (the file itself), it removes the file.

On MS platforms, of course, it just removes the file right away.

Wrong, _unlink() is non-standard, but remove() is. Use remove.

int _unlink( const char *filename ); // Notice the ''_''

That requires the C Runtime library; IMO it would be better to use DeleteFile() as it is implemented in the kernel... unless you really do need cross-platform support.

Hes not looking for cross platform support hes using MFC ffs

No matter how unstandard he does it... C:\\whatever automatically makes it not able to be crossplatform....

Well, there is DOS... I believe that would truly and technically qualify as a different platform. It''s a platform that wouldn''t support DeleteFile at least, but would support "C:\\whatever". Of course "cross-platform" may refer to ALL platforms and not just more than one platform.

My bad. unlink() is POSIX.1 which remove() is ANSI C, which makes remove() more standard.

I''ve been stuck in UNIX-land too long...
