Get filename from string-path?

Question

How do I get the filename from this string?

"C:\Documents and Settings\Usuario\Escritorio\hello\test.txt"

output:

"test.txt"

I really tried to find this one before posting, but all the results were contaminated, they talk about getting filenames from current dir (I must work with strings only)
