Guy,
I think you need to move the following lines outside the loop before the "for
(j=0; j<MyString; j++)".
StringArray=newArray(MyString);
FolderListPath=newArray(MyString);
These are making a new array each time through the for loop and you end up
with only the last one containing the last string.
I think you just need to create those arrays one time for that part of the
code at least.
Best,
George
