[MrMix]

Hello everyone,

I have hundred of folders and thousand of files to be renamed, here below a simple example of the actual structure of folders and files

John
¦_____ John - 2000 - NewYork Winter
¦ ¦______________ 01 Mainstr.jpg
¦ ¦______________ 02 PlazaHotel.jpg
¦
¦_____ John - 2001 - Boston April
¦ ¦______________ 01 ParkAve.jpg
¦ ¦______________ 02 SpargoPizza.jpg
¦
¦_____ John - 2002 - Miami Late Summer
¦
Part 1
¦______________ 01. SouthBeach.jpg
¦______________ 02. lobby.jpg
¦______________ 03. roofview.jpg
¦
Part 2
¦______________ 01. NorthBeach.jpg
¦______________ 02. restaurant.jpg
¦______________ 03. BeachByNight.jpg

and so on

Here below how it should be after the bulk rename of the files:
