What kind of links do you have? When you move around files, links tend to get broken. Do you have links with the full URL's or do you have relative links that used to work? I'm thinking that a find and replace can probably help you out here. But we do need additional information before I can tell what to do.
Thank you William. The links were pdf documents in the projects. When I republished to another drive, most of the older pdf’s in the project were no longer linked. We had to individually relink each one, over2000 files. I was just wondering, in case this happens again, if there is a better way to link them back.
