Renamer

Batch rename files, folders and extensions on Android. Pick a folder on your phone, SD card or in a cloud app, set your rules, check the live preview and rename hundreds of files in one tap. Made a mistake? Undo restores the original names.

WHAT YOU CAN DO
- Add a prefix or suffix to every name
- Find and replace text in file names
- Rename from scratch with a counter: leading zeros, start value, reset per folder
- Insert the date: today, creation or modification date, 8 formats, before or after the name
- Rename folders, and change or lowercase file extensions
- Include subfolders (recursive mode)
- Sort by name (natural order), kind, date, size or depth

SAFE BY DESIGN
- Live preview of the new names before you commit
- Conflict detection: duplicates, existing names, invalid characters
- Exclude single files from the batch
- Undo a rename in one tap, even after closing the app
- History of every batch, exportable as a text file

FAST
- Presets: save your rules once, reuse them on any folder
- Thousands of files without freezing
