You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
Create a new form, and in this create a single button. Attach code to this button so that when you click on it you see a message giving the name and size of the largest file in a given folder:
The sort of thing you should see when you run your program (see the notes below).
Notes:
- You can include the file path in your code as a constant.
- To look at the size of a file, use its Length property.
If you've got that working, try making the program recursive (so that it calls itself to search through not just the folder given, but also all of its subfolders).
