Creating a new subfolder and moving relevant files inside

Hi I would really appreciate a push in the right direction on this problem that I cannot manage to solve at the moment.
I have the following file structure
Customers/Customer No/
That always contain 2 files for every business transaction
1. date.Customer deatil.xls
2. date(+6). Customer order.pdf
For all future filing I have created rules that create the following folder structure:
Customers/Customer No/Customer Date
So I end up with just 2 files for 1 transaction in a subfolder called [Customer Date]
No problems so far. The future is dealt with
But it’s my existing files I am struggling with.
How Ican look at the many existing 2 group files that presently reside in the [Customer No] Folder and place them in a new created subfolder called [Customer Date] for each 2 corresponding files
In a nutshell if I have 30 xls files together with the 30 corresponding pdf files in the existing folder named [Customer No], how do I put the matched pair inside 30 new subfolders called [Customer date]
I am unsure if it’s particularly relevant, but I’ll mention it anyway, the newly created subfolder [Customer date] will always be named as the same date as that of the existing pdf file.
Thank you in advance for any assistance
