Bulk Rename Utility vs File Renamer

Bulk Rename Utility renames multiple files and entire folders in Windows using configurable rules. It can add, replace, or insert filename text, change case, alter extensions, and add dates or automatic numbers. A detailed preview shows proposed names before changes are applied. Rules can use photo EXIF data, MP3 ID3 tags, and Windows file properties. For more involved tasks, it supports regular expressions, JavaScript renaming, filters, subdirectory processing, and CSV input lists. The utility can create an undo batch file and save a log of renaming activity. Optional PDF and MediaInfo extensions expose document and audio/video metadata as tags, and require version 4.1.0.0 or newer. A portable version is available. The maker lists Windows 11, 10, 8, and 7, Windows on ARM, and specified Windows Server versions. Personal home use is free. Listed paid options include Home / Academic at $24.95 a month for one computer and a Commercial license at $92.95 as a one-time purchase per computer.

File Renamer is a free desktop application for batch renaming files on Linux and Windows. It is described as Free, Libre, Open Source Software under the GPL-3.0 license, with a free plan priced at free. Its documented workflow covers listing files, previewing changes, and viewing renamed files. The project wiki provides portable installation instructions for Linux and Windows and says this method needs no root or administrator permission. It also documents installation through pip with `pip install io.github.flossapps.file-renamer`, followed by the `file-renamer` command to start the app. Portable installation is reported as tested with Fedora KDE Plasma Desktop, Ubuntu Desktop, and Windows 11. Ubuntu 24.04.4 LTS requires `libxcb-cursor0`. Other desktop systems, including macOS, may work through pip but are untested.
