Preview dissapears after IPTC entry

Hi,

first of all, this is a great tool.

I just have one problem. On my Macintosh OSX 1.4.2 I have got a Photoshop EPS picture with preview. The preview is in the resource fork. If I now put a new IPTC entry with ./exiftool -Description=test srcfile, I lose the preview. Is this a mistake or can I first export the preview and then add it later back?

Best regards

Michael

Hi Michael,

To quote Known Problems on the ExifTool home page: "Some applications on Macintosh systems still store information in the resource fork of a file.  ExifTool does not process the resource fork, so this information is lost if the file is rewritten.  (In the same way that the Unix "cp" command will drop the resource fork in OS X versions earlier than 10.4)"

The only solution I can offer is to use the -overwrite_original_in_place option, which should maintain the resource fork of the original file.  However, be sure to keep a backup of your files since a copy isn't created when you use this option.
