Reading filenames and creating folders

Hey I was just wondering how I could read the filename of a folder or mp3. I want to be able to search the filename for a special character. Then create a folder unless folder already exist then just copy mp3 to the folder. TIA. Just needs some basic tips on where to get started with this.

CreateDirectory()

Not sure what you mean by "read the filename". If you mean enumerate all files/directories at a location, check out FindFirstFile() and FindNextFile().

Logging a directory.
