Sometimes a renaming job only needs to touch files of a specific type, all the JPGs in a mixed folder, or all the PDFs in an archive, while leaving other file types untouched. Working with files by extension lets you apply a renaming rule precisely where it belongs.
Turbo Bulk Renaming Tool lets you select and rename files by extension, applying prefixes, suffixes, find and replace, or numbering only to the file types you choose, while extension handling settings let you keep, force, or remove the extension itself as part of the same operation.
Because the live preview reflects exactly which files are included and how each one will be renamed, it's easy to confirm you're only touching the intended file types before committing. This approach works well for mixed folders where different formats need different renaming treatment.
Beyond the core workflow built for rename Files by Extension, Turbo Bulk Renaming Tool includes the full renaming toolkit found throughout the application: regex-based find and replace for advanced pattern matching, EXIF date extraction for photo libraries, case conversion for consistent capitalization, character trimming to strip a fixed number of characters from either end of a filename, text insertion at any position, and recursive folder scanning that pulls in files from every nested sub-folder. Any of these tools can be layered on top of the rules described above, so a job that starts as a simple rename can grow into a complete naming convention without switching to a different application.
The application itself is a one-time purchase for Windows 10 and Windows 11, with no subscription, no watermarks added to renamed files, and no data ever leaving your PC during a rename operation. Every batch can be logged to CSV, XLSX, or TXT so you always have a written record of the original and new name for each file, and any combination of rules you build can be saved as a reusable preset, so a renaming job you configure today is ready to run again in a couple of clicks the next time the same kind of files come in.
For teams and individuals who rename the same kind of files repeatedly, the combination of live preview, saved presets, and exportable logs turns rename Files by Extension from an occasional chore into a routine, low-risk step in a larger workflow. You configure the rules once, confirm the result looks right, and from then on a job that used to take an afternoon of manual renaming takes a few clicks, with a clear written record left behind for anyone who needs to check exactly what changed and when.

Can I rename only the PDFs in a folder that also has images?
Yes, select or filter to just the PDF files, and your renaming rule will apply only to those, leaving other file types untouched.
Can I rename different file types with different rules in the same folder?
Yes, run the renaming operation separately for each file type, applying a different rule to each as needed.
Does this let me both rename and change the extension for one file type?
Yes, combine a renaming rule with extension handling settings to change both the name and the extension in one pass.
Will the preview show only the files I've selected by extension?
Yes, the live preview reflects exactly the files included in your current selection.
Does this work on both Windows 10 and Windows 11?
Yes, Turbo Bulk Renaming Tool is built and tested for both Windows 10 and Windows 11.
Is my data safe when using this tool?
Yes, all renaming happens locally on your PC; no files are uploaded or sent anywhere, so private or sensitive files stay fully under your control.
Can I try a renaming rule without permanently committing to it?
Yes, the live preview lets you experiment with any rule and see the exact result before you click Rename, so nothing changes until you're ready.
Do I need to install anything else for this to work?
No, the installer includes everything needed; there are no separate dependencies or plugins to set up.
Can I rename files stored on an external or network drive?
Yes, you can select files from local drives, external drives, or mapped network shares, the same as any folder on your PC.
Can I cancel a rename operation partway through?
Yes, safe cancel support lets you stop an in-progress rename, and any files already renamed at that point stay renamed while the rest keep their original names.
What if I select a mix of files and folders together?
You can rename files and folders in the same selection; the same rule set applies to both, and the live preview shows the result for each.
Can I see exactly what changed after a rename is finished?
Yes, the exported rename log lists the original and new name side by side for every file, giving you a complete record of the operation even after the fact.
Does the tool support both files and folders in the same rule set?
Yes, the same prefix, suffix, numbering, and find and replace rules apply equally whether your selection contains files, folders, or a mix of both.
