RENAME - Multiple files - Macro or not Macro?

I work with multiple files that need renaming constantly.

Current Scenario:
* The original file names are always varied
* The renamed files have a specific location & specific name

The idea is to pick to click a button, select the file - Repeat 10x (there are 10 files in 10 different locations)
Press another button and it will rename and save all the files above in a different - single location.

EXAMPLE
File location: C:\TEMP\
File name: 123456 james document1.pdf

To be renamed, and resaved:
NEW File location: S:\TEMP\
File name: 123456 DOC1.pdf


** I have simplified the file names and locations above as in reality, it is more complicated and longer in characters.
