Filera

Overview

Filera is a desktop batch-renaming app for Linux, macOS and Windows. It suits people who need to apply several common filename changes across a folder tree without scripting. Its visual workflow and preview reduce guesswork, but the lack of undo makes a careful final check essential.

Key features

Filera arranges rename operations in a visual pipeline, including find and replace, number sequences, dates, custom text and case conversion. That is a useful approach for repeatable cleanup jobs: users can combine steps in one workflow instead of editing files individually. The no-scripting, no-regex design favors common transformations over workflows that depend on regular expressions.

A side-by-side view shows each old filename and its proposed replacement. Nothing changes on disk until the user applies the batch, giving them a chance to catch mistakes before committing. That safeguard matters, but it is not a recovery feature: Filera has no undo, so a mistaken rename can leave users without an in-app way to reverse it.

Filters can select files by name, type, date range or size; files that do not meet the filters are skipped. Filera can also traverse subfolders, making it more useful for batches spread through a directory tree. It can rename files in place, copy renamed files to another directory or move them there. Those output choices help separate a reorganization from the originals, although Filera cannot rename folders themselves.

Metadata-based renaming is supported, extending the tool beyond changes based only on visible filename text. Filera is built with Tauri and Rust, and its homepage identifies the software as MIT licensed.

Pricing

Filera is free: the Free plan costs nothing and is offered under the MIT License. There is no free trial because the product is free. That makes it a straightforward fit for individual users who want a desktop renamer without a subscription or paid tier; there is no stated free-plan quota or seat count to weigh.

Platforms

Filera runs on Linux, macOS and Windows. Linux installation instructions cover .deb packages for Debian and Ubuntu and .rpm packages for Fedora and RHEL. Users who prefer to compile it can build from source, provided they have Rust, Node.js v18 or higher and the platform's Tauri dependencies.

The Windows installer is not code-signed, so Windows Defender SmartScreen may display a warning. That is a practical installation hurdle for users who expect a signed installer, even though Windows is a supported platform.

Who it's for

Filera is best for desktop users who need to rename batches of files with a sequence of standard operations, want to preview changes first and value the ability to filter or process nested folders. It is less suitable for anyone who needs folder renaming, regex-based rules or an undo function to recover from an applied mistake.

Pros and cons

Pros

• Preview before applying: Old and new filenames appear side by side, while files stay unchanged until the user commits.
• Useful batch controls: Filters, subfolder traversal and several output modes help handle targeted jobs across directory trees.
• Free and MIT licensed: The desktop app has no paid tier or trial-to-paid decision.
• Cross-platform: Linux, macOS and Windows support gives it a place in mixed desktop environments.

Cons

• No undo: Users need to review the preview carefully because Filera cannot reverse an applied rename.
• No folder renaming or regex: Its scope is file names and visual pipeline tasks, not folder-name changes or regex workflows.
• Windows SmartScreen warning: The unsigned installer may prompt a warning during installation.

Alternatives

For a broader comparison, see File Renaming Software.

reNamerX is another free, MIT-licensed desktop batch renamer for Linux, macOS and Windows; it may suit readers comparing cross-platform free tools.

Renamer.ai is worth considering if a monthly allowance and Magic Folders are a better fit: its Starter plan is free with 25 renames per month, while Pro costs $9.95 a month.

Nomina, PBRenamer and Bulk Renamer are also free alternatives for readers comparing desktop renamers across Linux, macOS and Windows. PBRenamer uses GPL-3.0; Bulk Renamer is MIT licensed and has no account requirement.

Bulk Rename Utility is an option for Windows users willing to compare paid tiers, while Ant Renamer is a free Windows program with source code available.

ReNamer may fit non-commercial Windows users who can work within its free Lite limits of five renaming rules and five presets.

Verdict

Choose Filera if you want a free, cross-platform desktop tool for previewing and applying multi-step file renames across filtered batches and nested folders. Its strongest case is the combination of visual control and flexible output modes; look elsewhere if you need folder renaming, regex or a way to undo an applied batch.
