Review comment:
If you have direct access to the OS, you could try creating a name with
a leading space, and see how it appears in FTP.
You may need to escape or quote the space. Similarly with FTP, it's possible
that the client drops leading spaces.
"(((\\S+)\\s*)+)?"
could be expressed as
"((\\S+\\s*)+)?"
unless you need to refer to the non-space matches separately.
Unless trailing spaces need to be trimmed, it can be further simplified to:
"(.*)?"
because leading spaces have already been removed.
