How to overcome PathTooLongException?

Question

So I am writing a program that will scan for duplicate files on a computer as the programs that I've seen are really slow, and/or memory hogs, but I was running into a PathTooLongException when I tried to the whole drive. After reading PathTooLongException in C# code I became curious about the following two questions.

1. Would it hurt my performance if I were to switch my current directory every time I changed levels?

2. Is there a better way to get the directory structure of all the files (perhaps by calling something like tree.exe and then parsing that)?
