Bulk File Renamer

Bulk File Renamer is a focused Android app for renaming multiple files at once. Select individual files or a folder, create clear rename rules, preview every old name → new name change, and apply the bulk rename only when the result looks right. PREVIEW BEFORE YOU RENAME See the proposed filename for every selected item before anything changes. Previewing the full batch helps you spot unexpected results, check numbering and filename patterns, and confirm the rename before applying it. POWERFUL BULK RENAME RULES Batch rename files using practical tools such as: • Find and replace text • Add a prefix • Add a suffix • Add sequential numbering • Change filename case • Remove text • Trim characters • Replace spaces • Combine and reorder rename rules RENAME MULTIPLE FILES OR A FOLDER Choose individual files when you only need to rename selected items, or choose a folder for a larger batch. Filter and sort files before renaming to keep large rename operations easier to review and control. CONFLICT CHECKS BEFORE APPLYING The bulk file renamer checks proposed filenames before the rename starts. It can identify duplicate target names, naming conflicts, and invalid filenames so you can fix problems before applying changes to the batch. PROTECT FILE EXTENSIONS File extensions are protected by default while renaming files. If you intentionally choose to edit an extension, the app warns you first. Only file names are changed. The contents of your files are not modified. CLEAR RENAME PROGRESS AND RESULTS Follow the batch rename progress as the operation runs. When the rename finishes, see which files were renamed successfully, which failed, and which were skipped. Partial failures are clearly reported instead of being hidden. SAVE REUSABLE RENAME RECIPES Save useful bulk rename rule combinations for repeated tasks. A lightweight rename history helps you review previous operations, with undo or recovery available where Android storage behavior allows it. LOCAL, OFFLINE FILE RENAMING Bulk file renaming is processed locally on your Android device. The app uses Android's Storage Access Framework so you choose the files or folders it can access instead of granting broad storage access. USE BULK FILE RENAMER FOR • Renaming multiple files at once • Batch renaming photos and images • Adding sequential numbers to filenames • Numbering document collections • Cleaning downloaded filenames • Adding prefixes or suffixes to files • Finding and replacing text in filenames • Removing unwanted text or characters • Preparing files before upload or archiving • Standardizing filenames across a folder Bulk File Renamer is a dedicated file renaming utility. It is not a full file manager, storage cleaner, duplicate finder, cloud storage app, recovery tool, or archive manager. Rename files in bulk with more visibility and control. Preview filename changes, detect conflicts, protect file extensions, and rename multiple files when you are ready.
