I've been trying out about 20 different renamers this morning and finally have found one that looks good.
Is there a way to use EXIF data from digital pictures in the new name ?
I would like to have my pictures named yyyymmdd-hhnnss.jpg, where the value is the actual date/time the picture was taken !
It is a planned feature for the future.
Unless the creation or modification date of the files was kept, the current version won't be able to help you, sorry
