Copy all files in a folder to another folder under WinCE

In Windows, all files (including folders) in a folder are copied to another folder.

The algorithm is not complex and simple and practical.
// Szexistingdir: source folder
// Sznewdir: Target folder
// Note: The target folder must exist; otherwise, the function returns false.
Bool browseandcopy (const cstring szexistingdir, const cstring sznewdir)
{
Cstring szexistdir;

Cstring szaimdir = sznewdir; // Save the path of the target folder.

Cstring szfinddir = szexistingdir; // Save the source folder path.

If (szfinddir. Right (1 )! = "//")
{
Szfinddir + = "//";
Szexistdir = szfinddir;
}
Szfinddir + = "*. *"; // search all files

Win32_find_data FD;
Handle hfind;
Hfind = findfirstfile (szfinddir, & FD); // find the first file
If (hfind! = Invalid_handle_value)
{
Do {
If (FD. dwfileattributes & file_attribute_directory) // you can check whether a folder exists.
{
If (szaimdir. Right (1 )! = "//")
{
Szaimdir + = "//";
}
Createdirectory (szaimdir + FD. cfilename, null); // create a subfolder in the target folder
Browseandcopy (szexistdir + FD. cfilename, szaimdir + FD. cfilename); // recursively searches for files in subfiles
}
Else
{
If (szaimdir. Right (1 )! = "//")
{
Szaimdir + = "//";
}

If (copyfile (szexistdir + FD. cfilename, szaimdir + FD. cfilename, false) = false) // copy the file to the target folder
{
Return false;
}

}

} While (findnextfile (hfind, & FD); // you can check whether the next file exists.
}
Else
{
// If the source folder is empty, return
Return false;
} Return true;
