(I should also mention that for more complex formating, you could use sprintf() to create the "final" string, but in this case, a strcpy() and strcat() are sufficient, and probably more efficient than sprintf().

However, the best way to handle this is to move to C++. In C++ you should almost always use string classes instead of C-style (character array) strings. These are far safer and far easier to use. You could write uour own or use the STL string class, or a string class from another source. Similarly you should use the C++ file stream objects (fstream) in place of C I/O streams. These are also far safer and more powerful than C I/O streams.

for example;

string Location = "\\Dir\\";
string File = "filename.txt";
string Path = Location + File;
ofstream File2(Path.c_str());
