Change Attachment URL to File URL for existing posts !!

Hello,

I have a client who’s blog has currently has more than 2,500 posts and the client has inserted images on posts using by default the attachment link and not the file URL. In summary, when a visitor clicks on an image in my blog, the image will point to the attachment url.

I was looking to change the images url from attachment url to the file url. I know that this can be done manually, but since there is more than 1,000 posts, i’d like to know if is there a plugin or any way that i can do this in bulk.

Thanks in advance.
