Help! Getting clipping paths back on exported lightroom images!

Question

A bit of a problem.
I have 22,000 images, half of which were colour corrected in lightroom, but all 22,000 were exported from lightroom.
So, out of the 22,000 exported files I don't know which ones were colour corrected or not, which is not important until I realise that non of my clipping paths stayed with the exported files.
There were clipping paths on about 6,000 of these images.
So first, is there any way of finding from the exported files which ones were worked on in lightroom?
Secondly, is there a clever scripty way of bringing a clipping path from one photoshop file to another photoshop file (pixel perfect).... preferbly maybe having a folder full of doner files that have the clipping paths that a script gets their clipping paths and puts them onto the photoshop files in the second folder (the two folders will have files with same file names?)

Answer 1

Unless you specifically set Lr to overwrite the original export creates anew file, which doesn't include layers, clipping paths, Smart Objects and a bunch of other Ps stuff. Hopefully, your original with clipping paths is still around because that's the only way you're getting them back.
BTW: as you've discovered, editing an image in Lr after t's been edited in Ps is leaving yourself open to a world of hurt, especially when the image includes editing features that Lr doesn't support.
