This component can verify the existence of files or get all files of a certain extension. It uses the Directory.GetFiles method to get a list of all the files (uses SearchOption.AllDirectories to get files from all subfolders if option is present). Valid and invalid files are added to different collections and are outputted as arrays.

Example use cases:

*   Getting all pictures from a folder and it's subfolders
*   Checking if a list of expected Excel files are present before the start of a process which uses them
