Merging files (*.001, *.002 etc.)

I've got a problem with merging files. I don't know how to join files like: *.001, *.002 etc. from (for example) Total Commander using C++. Have you hot any ideas or suggestions?

These files should just be cuts of a larger file. In other words, begin with file 001 and write its contents to a new file called "assembledfile" for example. Then read the 002 file and append its contents to the "assembledfile" file.

In pseudocode:

Code:

---

int filecount = someFunctionToCalculateTheFileCount();
QFile assembled(fileName);
assembled.open(writeonly); //Check for errors too
 
if the file is open proceed:
 
for (int i = 0; i < filecount; ++i) {
    QFile file(fileNameBasedOnIteration);
    file.open(readonly) //Do some error checking too
 
    if the file is open read all its contents and write it to the assembled file. You might want to use a data stream if the files are binary!!!
 
    file.close();
}
assembled.close();
