Thanks Sergey,
I run the code on the volume with FAT file system (FDD) too.
The files weren't ordered by name.

I create files on FDD in this order:
TEST.TXT
FTEST.TXT
ATEST.TXT
BTEST.TXT

The result is:
TEST.TXT
FTEST.TXT
ATEST.TXT
BTEST.TXT
--------------------
Then I copy these files on C Drive (NTFS) and the result is:
ATEST.TXT
BTEST.TXT
FTEST.TXT
TEST.TXT
