Use only the first letter from a word

Hi all,



I'm creating a folder with values from some fields. It all goes OK, but, the only thing is that the name of the folder could get to long.

We use words like "Prototype Model" "Prototype Review" Next Date Review" "Next Prototype Review"

How could I end up with only the first letter from each word like "PM" "PR" "NDR" "NPR" ?



Greetings.
