So I'm developing a basic windows form HR Application.
I'm currently working on the load method, to load the text file collection into the program.
However when i run it i receive "Unable to load file"
Any help is much appreciated. Thank you

In the Load(String filename) function, catch the exception to see what the actual error is. It could be a simple directory issue.
