Answer to Question #41745 in Programming & Computer Science for chandan

Question

As part of her business activities, Sharon has created a large number of files and folders. Whenever she needs to view the details of the files stored in a folder, Sharon browses to the folder using Windows Explorer. However, she finds it cumbersome to browse to each individual folder to view the desired details. Therefore, she asks Hayley to modify the application to accept the name of a folder and display the following details of the files located in the folder: File name File size File creation date
Write the code that Hayley should write to create the desired file information viewer application.
