File Searching

This code will search a folder and all sub folders for a specified file or filter. Place all this code into a module.

To use this function:

Dim cFind As New cFindFiles
Dim cfList As New Collection

   Set cfList = cFind.DoFileSystemSearch("C:\Test", "*.*", PathsAndFilenames)

This will return a list of all filenames, paths or paths and filenames in a collection.
