I have a script where I have to replace the linked files by another set of files. I was doing this by reading the xmp information of the PSD, and replacing the Ingredients stRef:filePath property with the modified value and putting back the xmp into the file. Now when I open this PSD in Bridge, I get to see the updated links. But the links information do not update in Photoshop itself. I am not sure if I am missing out on something. Looking for urgent help as I am not very fluent with xmp scripting.
