Working with mp3 files and folders.
 

Hi,

Recently I came up with an idea of making my own program for tagging mp3 files. I realised I'm lacking in knowledge. For now I need the following information:

1. After typing a path to a main folder, I'd like to read the names of the folders inside.

2. Than I want to visit each of those folders - get inside (Those folders will include mp3 files).

3. Finally I want to enter this section of a mp3 file where the information about e.g. atrist or genre is kept and I want to chane it.

Can anyone help tell me with this?
Thanx!

the first 2 questions can be solved by the following sample code:

find(char * lpPath)

{

    char szFind[MAX_PATH];

    WIN32_FIND_DATA FindFileData;



    strcpy(szFind,lpPath);

    strcat(szFind,"\\*.*");



    HANDLE hFind=::FindFirstFile(szFind,&FindFileData);

    if(INVALID_HANDLE_VALUE == hFind)    return;

    

    while(TRUE)

    {

        if(FindFileData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)

        {

            if(FindFileData.cFileName[0]!='.')

            {

                strcpy(szFile,lpPath);

                strcat(szFile,"\\");

                strcat(szFile,FindFileData.cFileName);

                find(szFile);

            }

        }

        else

        {

            cout << FindFileData.cFileName;

        }

        if(!FindNextFile(hFind,&FindFileData))    break;

    }

    FindClose(hFind);

}

the information on artist in a mp3 file is stored in the last 128 bytes of the file. so you can simply read the last 128 bytes.
