Interface Overview

Filera uses a resizable two-panel layout. The divider between the panels can be dragged left or right to give more space to whichever side you need.

Left panel — File list

The left panel is where your files live. It shows every file you've loaded, along with a live preview of how each filename will look after the rename tasks are applied.

Key elements from top to bottom:

• Open Files / Open Folders buttons — load files into the session
• Search bar — filter the visible list by typing part of a filename
• Sort dropdown — sort by name, size, date created, date modified, or file type. Click the same sort column again to toggle ascending/descending order
• Clear button (trash icon) — removes all files from the session
• File table — two columns: Old Name and New Name. Files excluded by a filter appear dimmed and italicized
• Footer — shows the total number of files currently loaded

Right panel — Task pipeline

The right panel is where you build the rename logic. Tasks and filters stack vertically and execute from top to bottom.

Key elements:

• File Tasks & Effects button — opens the menu of rename tasks
• Filters button — opens the menu of file filters
• Templates button — access preset task combinations (coming soon)
• Clear button (trash icon) — removes all tasks and filters from the pipeline
• Task list — your active tasks, each with controls to reorder or remove
• Footer — output mode selector, output directory chooser, and the Batch Rename Files button

The preview loop

Every change to any task or filter triggers an immediate update of the New Name column. There is no separate "preview" button — the preview is always live.

Nothing on disk is touched until you press Batch Rename Files.
