How to rename .picasaoriginals subfolders

[xavierlh1]

I inherited my dad's Picture archives. Unfortunately, this contains a lot of subfolders named .picasaoriginals (i.e. just an extension with no folder name). When I try to modify image filenames across the entire data store (such as removing IMG_ prefix), files within these .picasaoriginals subfolders are not found or processed. Is there any way for me to rename these funky folders across the datastore using Bulk Rename?

Many condolences for your father...
Inside of Filters(12), could just put the checkmark inside for "Hidden" to see all hidden files/folders.
If its too dangerous, could add .picasaoriginals into the "Mask" to remove the folder(s) hidden attribute with Special(14).
