Scanning a directory is pretty easy, your OS will have a set of functions readily availible to do this with. Even changing the name isn't difficult. The problem is that without a massive data base of precompiled hashes how would you identify each song?

From the MP3 tag.

Here is MSDN's article on finding files in a directory: http://msdn.microsoft.com/en-us/library/aa365200(v=VS.85).aspx

It uses:

FindFirstFile(): http://msdn.microsoft.com/en-us/library/aa364418(VS.85).aspx

FindNextFile(): http://msdn.microsoft.com/en-us/library/aa364428(v=VS.85).aspx

and

WIN32_FIND_DATA: http://msdn.microsoft.com/en-us/library/aa365740(v=VS.85).aspx

I actually just use CopyFile(): http://msdn.microsoft.com/en-us/library/aa363851(VS.85).aspx to rename files, I think there is a "Right way" to do it but I'll have to get back to you after I look that up :P.

EDIT: I also use DeleteFile(): http://msdn.microsoft.com/en-us/library/aa363915(VS.85).aspx to clean up the old one.

The right way would be std::rename and std::remove:
