How Disk Tamer works

Create files from templates, rename batches with preview, update file contents, and run CSV-driven workflows from your browser without writing scripts.

Built for repetitive local file work. Choose a folder, preview the operation, and run repeatable changes with visible results.

Template-driven creation

Generate text files across selected folders with built-in placeholders and CSV-backed templates.

Preview-first batch changes

Review rename targets, confirm destructive actions, and inspect operation results without opening DevTools.

Local automation without scripting

Use a guided browser UI for repetitive file tasks that would otherwise require shell scripts or manual edits.
