[RndTbl] script for file copy

[VE4ER / Andy]

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


Thanks
Andy
