revUniqueID ??

[Glen Bojsza]

I was placing some images and set some custom properties when I
noticed that one of the images suddenly had a custom property of
revUniqueID?? cREVGeneral is the set it comes under but again the
documentation does not give details.

I am guessing that this can be used by the developer and that it's
function is similar to that of databases where it acts as a key.

I could not find anything in the documentation on this.

Has anybody used this for their project before?
