Prefix and suffix
Insert prefixes and suffixes into file names
Insertion is the fastest rule when you want to keep existing names and add context around them. Use it for project tags, backup labels, version numbers, and delivery markers.
Best for
Use this when the original names are useful but need project labels, version text, backup markers, or status words added around them.
Rename examples
Add prefix
document.pdf
backup_document.pdf

report.docx
report_v2.docx

image.jpg
image_approved.jpg
Common use cases
- Add project names to all files in a delivery folder.
- Mark backup, final, approved, or archived files.
- Insert version labels before the extension.
How to use it
- 1Choose whether text should be inserted before, after, or at a position.
- 2Enter the text to insert.
- 3Preview the result and apply the batch rename.
Limits and checks
- Decide whether inserted text belongs before the extension or at the absolute end.
- Keep separators consistent so the added prefix or suffix remains readable.
- Preview position-based insertion when file names have different lengths.
Common mistakes to avoid
- Adding a suffix after the extension when the intent is to keep the file type unchanged.
- Using different separators across multiple insertion rules.
- Inserting at a fixed position in a folder where names do not share the same structure.
