Upload attachment directly into a directory?

[leon2u]

Well I run a forum and now I want that users can upload attachments larger then 1 Mb in their posting. There is a restriction in mysql for 1 Mb and php for 2 Mb and because I am on a shared server I contacted my provider. He is giving me a hard time to change te settings in sql...he says that it is better to upload attachments directly to a folder.

My question is:

Can someone tell me what to change in the php code so that it does not stores the attachements into the database but into a directory called "attachments" or so.
I use the standard upload which comes witch comes with Vbulletin and on editing postings I use this ADD ATTACHMENT ON EDIT POST HACK version 1.1 - by Tommy Boy

Let me know, thanks for your effort in advance...
