Introduction

Filera is a fast, cross-platform batch file renaming tool built with Rust and Tauri. It lets you rename hundreds of files at once using a visual pipeline of tasks and filters — with a live preview of every change before you commit.

What makes Filera different

Most batch renamers force you to write scripts or regex patterns. Filera takes a different approach: you build a pipeline of tasks using simple controls, and you see the old and new filenames side-by-side in real time. Nothing is renamed until you click Batch Rename Files.

Key capabilities

• Batch rename any number of files in a single operation
• Live preview — see old name → new name before applying
• Task pipeline — combine multiple rename tasks in any order
• Filters — exclude files from the batch by name, type, date, or size
• Recursive folder support — open entire directory trees at once
• Drag & drop files directly into the app
• Output flexibility — rename in place, copy, or move to a new folder
• Cross-platform — runs on Windows, macOS, and Linux

How it works

Filera's interface is split into two panels:

• Left panel — your file list. Load files, search, sort, and see the rename preview here.
• Right panel — your task pipeline. Add rename tasks and filters that transform filenames in sequence.

Every time you change a task, the preview updates instantly. When you're satisfied with the results, click Batch Rename Files to apply all changes.
