Downloading attachments from an old IPB

Hi, new member here.

I have a really old installation of IPB that I haven't used for 7 years or more and I'd like to download all attachments from the board.

From having looked at ibf_attachments through phpmyadmin, I can see the file names and what .IPB files these correlate to (I'm assuming that everything but images have been converted into .IPB). However, downloading these files manually would be pretty tedious since I'd have to rename the file endings as well (assuming that this even works ...).

Do you have any recommendations on how to get this sorted? Maybe the easiest would be to overwrite the old IPB installation files with a newer version and then use the Attachments feature through IPB's Control Panel?

Any help would be appreciated, thanks.
