Where are saved the changed metadata in Lighroom ver 3.3

[akowalsk]

Hi all,

Im using Photoshop Lightroom ver. 3.3. So I change some RAW photos and now would like to export them. 
Thats all not the problem. It is working fine.
But where are saved all the data of changes photos? The importet RAW file is no changes and not touched, so Im looking for XMP files or something similar: not found. Looking in the help and contact the support but there is nothing regarding this.

The idea is, to save the fotos and matadata/changed properties etc. on external drive for using later and get free of space of this 20GB.

many thanks in advance.
BR, Arthur

You change the export option to, "Original + settings".
