Thread: parsing a string

I have 2 strings like this:
In these 2 cases I want to get "File1.txt" and "File2.txt" and put them to a new string.
I need the same method so I suppose I have to find the Last "/" in the string and then
put the rest to a new string.

What method and approach could be used to do this ?

Code:

std::string Line1 = "c:\Folder1\File1.txt";
std::string Line2 = "c:\Folder1\Folder2\File2.txt";
