Check the return status of the move function (I assume you are using File::Copy): 
   move($bookFiles[$h], $dir . "/Book Chapter/" . $bookName . "/" . $b
+ookFileName[-1]) or warn $!;

[download]
Typical reasons are: the input file is not found or you do not have permissions to write to the directory or clobber an existing file.

From the File::Copy docs:

All functions return 1 on success, 0 on failure. $! will be set if an error was encountered.
You should also check the return status of the preceding mkdir.
