How to import ZoomBrowser EX comments to DPP4

Help !

I have about 10 000 pictures of birds for which identification info is in the Comment field of ZoomBrowser EX. This info does not appear in the Comment field of DPP4. 
How can I proceed to migrate the infos in ZoomBrowser to DPP ? Is there a dedicated script allowing to export this Data from ZoomBrowser an import it in DPP ?

Thanking you in advance,

Patrick

I do not use ZoomBrowser EX, but there are some comment tags that are common in JPEG metadata.

I use exiftool to display and change metadata. I suggest using exiftool to extract the comment and copy it to the description tag which seems to be supported by newer software.

Quoting:

Comment is the very old jpeg COM block. It dates back to the beginning of the jpeg format and is not part of any other standard. It is very fragile, as some programs will overwrite it to place the name of the program. For example, Photoshop used to write "File written by Adobe Photoshop" there, overwriting anything that used to be there. IMO, using it should avoided.

UserComment is part of the EXIF standard. Very few programs use it and it's very unlikely to be overwritten. It's usually set manually through the camera at the time the image is take. At least that's the case on my old Nikon. Not many programs read it, though.

I'd suggest skipping UserComment, as it's not widely supported in most software. The XMP:Description tag is a better location.
