I have a massive number of files within a massive number of folders (several 100,000 files; 5000 folders & subfolders). I need to re-name all of the files. Simply giving them consecutive numbers or a combination of letters and numbers (e.g., first file called "ER000001," the second called "ER000002," and so on) will be sufficient for my purposes.
I've found utilities that do re-naming within a single folder, but none that go through a tree structure.
I need this for my business, so there's no problem paying more than I would for something just for my home computer.
Can anyone suggest a program that does this?
Thanks.
