How to use Find and Replace File Names

  1. Add the requested files.
  2. Review the options and the displayed queue.
  3. Select Replace in Names, inspect the result, and download the generated ZIP.

What this file tool does

This tool changes names only, preserves file bytes and extensions unless the matched text includes them, and resolves duplicate output names.

Build a safe literal or regular-expression matcher, transform each name, validate it, and package renamed copies.

Regular expressions can match more than expected. The originals are never renamed; the ZIP contains new copies.

Supported inputs and limits

The tool works with files exposed through the browser picker. Actual limits depend on available device memory and browser support.

Example and practical tips

Practical example

Replace draft with final in a batch of project files while keeping every file's content unchanged.

Tips

  • Keep an untouched copy of important source files.
  • Review the result list before using the download.
  • For large batches, test a small sample first.

Frequently asked questions

How do I replace text in many file names?

Add the files, enter Find and Replace with values, and download the renamed ZIP.

Can I replace every occurrence in a file name?

Yes. Choose All literal matches, or use a regular expression for advanced patterns.

Can the search ignore uppercase and lowercase differences?

Yes. Set Case-sensitive to No.

What happens when two names become identical?

The tool appends a number so the ZIP does not overwrite an earlier file.

Does find and replace edit file contents?

No. Only output file names change; the bytes remain intact.
