list all the files in a folder

In short:
To list all the files in a folder or directory using the .NET Framework's methods in the System.IO namespace and the C# programming language, the framework provides powerful methods on the Directory class that can help you list files on the filesystem. The Directory.GetFiles method allows you to get a string array of the file names.
Please refer:
C# Directory.GetFiles[^]

This example shows how to get list of file names from a directory (including subdirectories). You can filter the list by specific extension.
Get Files from Directory [C#][^]

Hi
see project

MP3-Rearrange

See class RecursiveIO. That will search a directory tree. Remove the call to method subRecurse in method subRecurse if you want the specified directory only.

You can override method ProcessFileName to write to a comma separated text file which Excel can easily import.
