I am trying to meta-tag our archives and i have issues when tagging files that are over 5 or 6 years old. Bridge will not let me append metadata on PSDs or Tiffs. Occasionally it kicks back an error on jpegs too. These are files that have been sitting on a server for years, untouched. sometimes i have to open them, re-save them in CS5 and then append metadata. Why won't bridge write metadata to old files?

Hi Joshua,

I can hazard a guess: Bridge is trying to store the metadata in an XMP packet embedded in the file. Typically this XMP packet is saved with padding in the event metadata needs to be added. The padding gives Bridge the ability to expand the metadata without altering the rest of the file, assuring its validity. The problem with the older files is that they are either missing their XMP packet or the packet was saved without the extra padding. In either case Bridge would have to shuffle items around in the file to make room for the new metadata which it is reluctant to do for fear of corrupting the file.

By opening and re-saving the files in Photoshop CS5 the XMP packet is given the extra padding needed by Bridge to append the metadata. Once the padding is properly inserted, Bridge is able to modify the metadata while leaving the rest of the file's structure untouched.
