Can't edit metadata in large file

[RDB_Mac]

I have a large file (3.08 GB .pst) and Bridge will not allow me to edit the metadata.  I get an error that says "This property cannot be modified." Any idea why I am getting that warning?  It is my original file - scanned copy of an image for a restoration.  Thanks!

Check the preferences, and make sure this value is greater than your file size.
