Hi all,

i am quite new to ruby and I was wondering if there is a method in ruby 
to get a list of folders and subfolders.

e.g.: I have a 'root' directory and some sub directories and finaly some 
data files.

---root
     |---sub1
     |     |----sub1A
     |     |       |----data.txt
     |     |
     |     |----sub1B
     |             |----data.txt
     |
     |---sub2
     |     |----sub2A
     |     |       |----data.txt
     .     .
     .     .
     .     .
   and so on.

is there a way in ruby to get a list of all subdirectories, or maybe a 
string to each data.txt (this name doesnot change)

The problem is, that i don't know how many 'data.txt' there are , and so 
i would need a method that searches in all subdirectories(starting at 
'root') for this file and returns an array of strings with the path to 
each file.

Is there maybe another way to do this?

Thanks a lot!

best regards,
Roman
