write a script in js to copy one particular file from many sub-folders to a separate folder

My requirement is:

Architecture - one session file contains 40 subfolders, each subfolder has 5 files among which only one is text file will present .All sub-folders have similar nomenclature - i want to copy every abc(timestamp).txt file from all the sub-folder of that session to separate folder

Can any one please help me to write script so that i can copy all those text files in sub-folder to one separate folder?

Really it take lots of time & effort to make sure all those abc(timestamp).text file are copied to one folder.

Thank u so much in advance.
