Ant Renamer vs Filera

Ant Renamer is a free Windows program for applying rules to large batches of file and folder names. Its actions include changing extensions, replacing or inserting text, moving or deleting characters, numbering names, and changing letter case. It can build names from MP3 ID3 v1.1 tags, modification dates and times, EXIF information, regular expressions, or names in a supplied list or file. The program changes names only, not file contents. It supports Unicode names, including Japanese, Chinese, and Arabic characters, on NT systems. The interface is available in English and numerous other languages, including French, German, Japanese, Portuguese, and Tamil. Ant Renamer is free software under the GNU General Public License version 2 or, at the user’s option, a later version. Version 2.13.0 is offered as an installer and as a portable ZIP package. The project began in 2003 and is still maintained, though its maker describes it as based on old tools and not using newer Windows features. The maker points users to the included help file, online manuals, a forum, or email support.

Filera is a free batch file renaming tool for Linux, macOS, and Windows, designed to rename hundreds of files at once. A visual task pipeline offers find and replace, number sequences, dates, custom text, and case conversion, without scripting or regex. Before applying a rename, Filera shows old and proposed filenames side by side; files on disk remain unchanged until you apply the operation. Filters target files by name, type, date range, or size, and filtered files are skipped. Filera can walk directory trees and subfolders in one pass. You can rename files in place, copy renamed files to another directory, or move them. The app supports metadata-based renaming, but not regex renaming, folder renaming, or undoing changes. Built with Tauri and Rust, Filera is MIT licensed. Linux installation instructions list .deb packages for Debian and Ubuntu, and .rpm packages for Fedora and RHEL. Its Windows installer is not yet code-signed, so Windows Defender SmartScreen may show a warning.
