[RndTbl] script for file copy

Can anybody suggest a script to copy files from one directory structure to another changing the filename in the process to include the original folder names, but only if an actual file with extension exists in the bottom child folder :

Go from :

Master Folder ------> Sub Folder1 -----> Sub Sub Folder1 ---> filename.example ------> Sub Folder2 -----> Sub Sub Folder1 ---> filename.example ------> Sub Folder2 -----> Sub Sub Folder2 ---> filename.example

To:

/Var/MainFolder/Master_Sub1_SubSub1_filename.example /Var/MainFolder/Master_Sub2_SubSub1_filename.example /Var/MainFolder/Master_Sub2_SubSub2_filename.example ....etc
