Rename the pdf file inside sub-directories to the name of the sub directory

Rename the pdf file inside sub-directories to the name of the sub directory

I am using win 7 platform. Need your help to create a bat file which
simplifies my job. My folders and files are arranged in this structure.
File1
folder1 ->abcd.pdf folder2 ->shhd.pdf..............................
folderN ->gfdfgd.pdf
File2
folder1 ->gbg.pdf folder2 ->kjc67z.pdf..............................
folderN ->iuxz4i.pdf
--
--
--
FileN
folder1 ->ah455.pdf folder2 ->jfhd45.pdf..............................
folderN ->juvxzr.pdf
I want to generate a batch file which renames the pdf file to name of the
folder it contains. For example, in the above structure "abcd.pdf" is
renamed to folder1.pdf. Respectively this is done for all pdf files.
Also a folder named "test" is created inside each
directory(file1,file2..etc) which contains all the renamed pdf files of
its respective directory.
