The metadata is stored in a database. To create the xmp files you need to either explicitly export them (Metadata>XMP> Export XMP Metadata to File), or tick the preference setting in the Metadata area of the File Management tab.
However, why do want to export the metadata? Do you want Bridge to use the xmp files? Do you want to import to another Lr database?
thank you for your answer, great to know~!
i have been a capture one user and was used to having a folder that holds all my changes, right in the folder that holds the raw files. the fact that everything is sitting in a database seems a bit limiting. i used to be able to bring a folder and open in on any comp with c-one and voila, all my changes where still there...
i guess the previews are stored in the database also?
which settings do you recommend for creatinbg previews?
thank you for your help
