## Description

Renamer is a powerful Chrome extension designed to simplify file management by enabling bulk renaming and extension changes. Users can rename multiple files by adding sequential numbers while preserving their extensions or change the file extension of all files in a folder or selectively by existing extension.

Additional operations include search and replace of words within file names (including extensions), modifying the nth character in file names, and appending prefixes or suffixes to multiple file names at once. This tool streamlines the file renaming process, saving time and reducing manual errors for users handling large volumes of files.

## Review summary

Users generally praise the app for its powerful, fast, and user-friendly bulk renaming functions, particularly for changing file extensions and replacing text across many files at once. However, several reviews mention limitations such as inability to batch-rename folders, occasional failures when processing very large file sets, and absence of an undo option. Some users suggest improvements including better guidance, additional features like dark mode and renaming by date, and fixes for permission/access issues. Overall, it remains a highly recommended tool for bulk file renaming on Android.
