Thread: Problem related to file handling example

Can you explain what problems you are having and ask some specific questions about your task?
What steps for the task have you completed and tested?
What steps need to be done?

Work on the problems one at a time: search the file in D drive
What steps is the code taking to do that?

OK, is that working? If not where are you having problems?
Where does the code test for subdirectories and search them?

For developing and testing the search code, write a small simple program to do that without any GUI. It should have just the code for the search.

Start by making a small program with a method that searchs for the desired file. After you get that to work, the code/technique can be copied to the larger program.

You need to decide on the steps the program should take BEFORE writing code.
