Thank you guys, for your kind inputs! =) it really helped me alot!

However, I now encounter another problem..
Assuming my hash:
ex = {}
ex[0] = [".xls", ".ini", "20080326"]
ex[1] = ["RVG", ".xls", ".rb"]

I need to extract the values in each array with the extentions(values 
with periods) into one string and the dir names(values without the 
periods) into another string. I've been tryin to figure out but to no 
avail, is there a clean way to do that?
