There are two things wrong here.
First when you:
>
set x to thisfilename
You redefine x as a string object. It is no longer a list.
Instead, you need to:
set x to {thisfilename}
to maintain its list class.
Secondly, when embedding lists, you need to:
set y to y & {x}
Enclosing the sublist in {} adds it as a list rather than as a string
object.
set x to {}
set y to {}
set x to {thisfilename}
set y to y & {x}
class of item 1 of y -- returns "list"

Each time I do it the concatenation seems to put the names back as strings.
