Photoshop/corrupted by Mac?
 

Nikon D2X, Photoshop CS2, Mac

Over the past couple of years I’ve always shot in RAW - made any changes that I needed to do and then done a batch conversion to Jpegs into a new folder. Today the changes which I’ve made to the Raw files have not been carried out when they have been converted to Jpegs.
The problem seems to be the fact the XMP (corrections) files now dont seem to be ‘attached’ to the original RAW file as they won’t change folders when you move it.
Moving a modified RAW photo one at the time - confirms this problem - the changes are not carried over into a new folder.

Have not added any new software/updates since it last worked perfectly..

Have reinstalled CS2 and latest photoshop RAW plugin and tried earlier photos which worked without a problem - but now they are also not keeping their corrections when moved into a different folder...

Any thoughts?
