ReNamer
A Windows file renamer with ordered naming rules, a personal-use Lite edition and paid Pro licensing.
About ReNamer
ReNamer is a bulk file renamer for Windows. It applies a sequence of renaming rules to a set of files in order, so the user controls the final filename. Standard rules cover inserting or removing text, replacing text, changing case, adjusting file extensions, adding sequential numbers, and cleaning up names. Rule sets can be saved as named presets and reused. Filenames can also be built from file content, using tags such as music, photo, video, and document properties, as well as checksums. Folders can be renamed alongside files.
Advanced options include Regular Expressions for pattern-based renaming and a Pascal Script rule for custom logic and integration with external tools. The source describes these as options for advanced users. The product requires Windows 2000 or later. The directory lists a personal-use Lite edition and a paid Pro license, but the source does not state which features each edition includes.
