How to Rename Files With a Suffix

A suffix added before the file extension is useful for marking a version, status, or category — for example, tagging a batch of images with "_draft", "_final", or "_v2", or labeling exported reports with "_2026". Suffixes work well when you want the original filename to stay readable at the start, with the extra context appended at the end.

Manually editing each filename to add the same suffix is slow and easy to get wrong, especially when the suffix needs to go precisely before the file extension rather than at the very end. A renaming tool handles that placement automatically across an entire batch.

1. Install Turbo Batch File Rename Tool on your Windows PC.
2. Open the app and load the folder containing the files you want to modify.
3. Select the Suffix renaming rule, or use Insert at Position set to just before the file extension.
4. Type the text you want to add as a suffix, such as "_final" or "_v2".
5. Check the live preview to confirm the suffix is placed correctly before the file extension on every file.
6. Click Rename to apply the suffix across the entire selected batch.

• Suffix is inserted correctly before the file extension, not at the very end
• Apply the same suffix to an entire folder of files in one action
• Live preview confirms exact placement before any files are renamed
• Can be combined with other rules, such as Find & Replace, in sequence
• Recursive sub-folder support for nested file structures
• Conflict detection and Undo provide a safety net for the whole operation
