Hide listing of all childfolders in parent folder but show childfolder's content, or simply writing something like below in the .htaccess of parent folder...
IndexIgnore * (except childfolders+their content)
Directory structure:
parent >
child 1->something.pdf
child 2->anything.pdf
...
...
child n->another-something.pdf
now to the user when he goes to parent, then nothing should be visible but when he goes to parent/child [1 to n]/ he should see the corresponding pdf.
(also childfolders are dynamically generated and are very large in number !)
