We need a .NET app that will take a directory. The app would then open every .CSV file in the given directory, change and then delete the changes, and save the file (this is to give the CSV file a more up-to-date timestamp). After saving, the app needs to ZIP the CSV file in the currently directory using the CSV file name. If that name is already there, the new ZIP file would need to over write the old one. The app would need to have a status bar and also produce a file or window that shows the changes made. Thanks!
