You can do this from the command prompt using the command copy *.* newfile. To do this programatically, open the destination file for writing using CreateFile. Use FindFirstFile / FindNextFile to enumerate each file in the folder. For each file found use CreateFile to open the file for reading. Call ReadFile to read the entire contents of the file for reading and then use WriteFile on the destination file to write the contents that were read.

If you're using C++ you can combine files fairly easily. Open each one as an istream, open the destination file as an ofstream and then insert the streambufs of the input files to the destination file. Something like:

std::ifstream a( "c:\\\\a.txt" );
std::ifstream b( "c:\\\\b.txt" );

std::ofstream c( "c:\\\\c.txt" );
c << a.rdbuf() << b.rdbuf();

will concatenate a.txt and b.txt and dump them in c.txt. It saves loads of tedious mucking about with C functions or Windows API functions. Cheers, Ash
