Regex question

[Bruno Veldeman]

Hi,
 
I can't seem to get the regex right for this:
 
I have a string with this format "/blabla/dir/nextdir/name.txt"
I want only 'name.txt' in one string and the rest in another string.
 
It would be nice explaining the regex in plain english.
 
Or better, how do I learn to use regex?
 
For now it's like chineese to me.
(And I don't know chineese ;-) )
 
Thanks.
