I solve it! For anyone that wants to know.

1) Ftp Server
Create a copy of newattachment.php --> newattachmentmine.php

2) VBulletin Templates
Create a new clone of newattachment, newpost_attachment, newpost_attachmentbit, newpost_attachment, newattachment_errormessage, newattachment_keybit, template, for example newattachmentmine, newpost_attachmentmine, newpost_attachmentbitmine, newpost_attachmentmine, newattachment_errormessagemine, newattachment_keybitmine.

Into this templates replace the value newattachment.php with the new newattachmentmine.php file.

3) Form Hack PHP

Replace the values newattachment.php, newpost_attachment, newpost_attachmentbit to the new one newattachmentmine.php,newpost_attachment_mine,newpost_attachmentbit_mine.

4) In this file newattachmentmine.php replace all this templates newattachment, newpost_attachment, newpost_attachmentbit, newpost_attachment, newattachment_errormessage, newattachment_keybit, with the new.

Also find this code (normally in line 79)

PHP Code:

// No permissions to post attachments in this forum or no permission to view threads in this forum.
if (empty($vbulletin->userinfo['attachmentextensions']) OR !($forumperms & $vbulletin->bf_ugp_forumpermissions['canpostattachment']) OR !($forumperms & $vbulletin->bf_ugp_forumpermissions['canview']) OR !($forumperms & $vbulletin->bf_ugp_forumpermissions['canviewthreads']))
{
     print_no_permission();
} 


Remove this from the if.

PHP Code:

OR !($forumperms & $vbulletin->bf_ugp_forumpermissions['canview']) 


Like this.

PHP Code:

// No permissions to post attachments in this forum or no permission to view threads in this forum.
 if (empty($vbulletin->userinfo['attachmentextensions']) OR !($forumperms & $vbulletin->bf_ugp_forumpermissions['canpostattachment']) OR !($forumperms & $vbulletin->bf_ugp_forumpermissions['canviewthreads']))
 {
     print_no_permission();
 } 


After that if you change the permission setting in a forum "Can View Forum = No" and the others yes. Users can post the form and can attach files normally, but they can’t see the answer post.

I think maybe it’s useful for someone this trick.

P.S. Be careful, because if you don’t do that correctly may you corrupt the form or the attach option of your site.
