MyBB Community Forums

i want to upload my files to my host and don't use original methode of mybb in uploading files
i mean i want to change the methode of mybb to my own
originally in mybb files are uploaded by this methode:
example.zip ==> 1234566_example.attach
but i love to use this methode:
$filename= "attachment id"+"file_name"+"file_ext"
like : example.zip ==> 35example.zip
so i want to do this and change the attachment download link in posts like this:
www.website.com/attachmen.php?aid=45 ==> www.website.com/uploads/35example.zip
i hope explanation is enough

Actually, MyBB renames the files for security reasons (so attackers don't upload and execute scripts on your server).

so how can i add resume cabability to my files
i mean when i want to download attached files i can't pause downloading it and resume later

Ever seen a FORUM system have a resume feature for downloading attachments ?
Files are like between 10kb && 2mb ...
