I am trying to embed the IPTC metadata into some files.  It’s giving me an error that I can’t do it because the files are locked or I don’t have permission to modify them.  I’ve checked the info on the files and they’re not locked, so I’m confused as to why this is happening.  What else can I check?  I’ve been trying to find the answer to this and am coming up empty-handed, so I’m hoping you can help me.
