JSL how to delete folders based on LastModificationDate

Question

Hi, using JMP Pro 13.0.  I am a JSL newbie so I know my coding isn't super efficient but I just need functionality for some personal scripts.  I have a lenghtly script and in this one part I'm in need of copying a directory from another drive to a local work drive.  First I purge the local work drive then do the copy.  I don't want to copy the entire directory, just folders within that are -N days old.  Is this possible?  And "DirA" and "DirB" of course are substitutes for my drive locations.

SPath = "DirA";
LPath = "DirB";
LSubPath = "DirB"||"\DirC";
Delete Directory( LSubPath );
//Below is where I would like to only copy folders within SPath that are -N days old
Copy Directory (SPath, LPath);

Can you copy files based on their creation date? This might be too slow as for only a few thousand files it took ~30s to generate a list (not copy).

Something like below:

namesdefaulttohere(1);
filelist=filesindirectory("DirA");
for(i=1,i<length(filelist),i++,
	if(datedifference(creationdate("DirA\"||filelist[i]),today(),"Day","fractional")<10,
		copyfile("DirA\"||filelist[i],"DirB")
	);
);
