Bulk Rename Utility

Hi Guys,
I am a newbie, need help in renaming 50000 files.
I have a folder and it has more than 150 sub folders.
I want to scan the root folder and make sure all files under the root folder must maintain a unique file name no matter in which sub folder they are.

It will be better to show preview, and show me before and after name change.

Please help.

Thank you,

12:Filters, enable Files & Subfolders (disable Folders)
2:Name -> Remove
10:Numbering -> Prefix

(then) Set your parent directory

Should give you a list of filenames, 1..50000.ext.


Copy a few of the directories elsewhere & test first.
