Bulk Rename Utility

Batch File Rename Utility is an easy-to-use file renaming program (also known as a file renaming tool). Renaming multiple files and/or folders has never been easier!

Thanks to its low memory usage, it can be left running continuously without consuming all your memory. Initially developed as a free Visual Basic tool, its popularity led to it being completely rewritten in C++ to be robust, lightweight, and capable of handling large folders/disks with many entries very quickly! It can rename over 100,000 files in batches... and thousands in seconds.
