I've lost, after a "format and reinstall", a simple panel in Adobe Bridge.

This panel plug-in copy, paste and save from old to new photos, 3 most important metadata fields: keywords, title and description.

Do you have a link to this panel ?

Thank you in advance !

If I understand what you are asking, try this:

Select the "Window" menu, and look for a checkmark next to "Metadata Panel". If there isn't one, click on it, and the panel should appear. If there is one, then I don't know what the problem might be.

Agree with KB. The fields title, description and keyword are accessible from Metadata panel. Click check mark on MetaData panel from window menu, if it is uncheck.

I have also selected only title, description and keyword fields from Edit > Preference > MetaData > IPTC Core leaving all oher fields uncheck. It is very handy to view and edit only these three required fields.

I got understood what you are saying i also had faced it ..I also uninstalled it and after this I lost.

I tell you what you have to do !! So first go to the ''Windows menu'' and click to the Metadata Panel..If it shows then here you can easily get the panel otherwise, there is another problem and you have to completely reinstall it "
Thanks you
