USE CASES

When to use Batch rename files?

Build a naming convention for a batch, control numbering order and collisions, then export renamed copies without touching the originals.

  • Normalize photos or attachments before archiving
  • Add a consistent date and sequence to a batch
  • Replace a legacy prefix across several files
  • Prepare a batch for upload to a business application

Your data stays in the browser

Processed content is not uploaded to WorkToolset. Required libraries may be loaded by the site, but the file stays in the browser.

GOOD TO KNOW

Limitations to know

  • Original files are never renamed or moved: WorkToolset only creates a ZIP of copies.
  • The {date} token uses the modification date exposed by the browser and does not prove a business date.
  • Changing only a filename extension does not convert the file contents.
HOW IT WORKS

A straightforward workflow.

  1. 1Add files and choose a preset or build your template.
  2. 2Reorder the batch: numbering follows that exact order.
  3. 3Review collisions, changed extensions and any manual names.
