New · Version 2
The major update
From renaming tool to complete file workflow.
rsk.rename 2 goes far beyond search and replace. Combine rules, inspect results live, save workflows, and automate them when needed.
Try version 201New features
Rules without limits
Combine replacement, numbering, dates, metadata, regular expressions, and custom JavaScript logic.
Copy and move
Do more than rename files—organize them in the right location within the same workflow.
Presets and command line
Save recurring jobs and run prepared workflows automatically through the CLI.
02
Technical improvements
- Optimized processing of large file sets and complex rule chains
- Earlier detection of naming conflicts and problematic results
- Repeatable automation of saved presets through the command line
03
Completely redesigned
- Rebuilt rule editor for both quick and advanced jobs
- Direct before-and-after comparison in the result preview
- Clear separation of file selection, rules, review, and execution
Professional file processing
Bulk file work is not a manual task.
Large file sets need a repeatable, controlled process.
Photos from different sources, cryptically named exports, or documents that must follow a fixed schema: rsk.rename processes entire folders using precise rules.
Review the result in the preview, save recurring processes, and automate them through the command line when needed.
How it works
From rules and preview to controlled execution
Select your files and define exactly what should happen to them.
Next, you build your rules. Simple replacements, numbering, date values, metadata, regular expressions, or custom JavaScript logic can be combined with one another.
Before rsk.rename changes anything, you see the result.
You only carry out the process when everything is right.
1. Select files
Add individual files or entire folders. You can see exactly what you’re working with.
2. Establish rules
Build exactly the workflow you need. One rule or several in sequence—ranging from simple replacement to custom logic.
3. Check result
The preview shows you the new file name and potential conflicts before any actual changes are made.

What you can get done
What can you do with it?
Quite a lot. Here are a few typical jobs for which I would have built rsk.rename myself.
Name photos neatly
For example, IMG_4821.jpg , IMG_4822.jpg , and IMG_4823.jpg become:
Sommerfest_2026_001.jpg Sommerfest_2026_002.jpg Sommerfest_2026_003.jpg
Shaping exports
Remove cryptic elements from filenames, add a date, or bring regularly generated files into a consistent format.
Reorganize files simultaneously
Don’t just rename files; copy or move them directly to the right location.
Save recurring jobs
If you regularly need the same workflow, simply save it as a preset and use it again next time.
And if your use case becomes more specific, regex, JavaScript rules and the command line are available.
Features
A complete toolkit for large file sets.
11feature areas
From quick replacements to metadata, JavaScript, presets, and CLI automation, rsk.rename covers both everyday jobs and advanced workflows.
01Guided four-step workflow+
- Select source, define target and mode, configure rules with preview, and execute with control.
- Add files and folders by drag and drop, optionally including subfolders and folders themselves.
- Review source, target, method, file count, and rule chain in a final summary.
02Flexible rule pipeline+
- Edit prefixes, suffixes, replacements, letter case, whitespace, characters, and freely positioned text.
- Move substrings, change extensions, and number with start, step, padding, folder reset, decimal, hex, or Roman formats.
- Combine, enable, disable, and reorder any number of rules by drag and drop.
03Regex, tokens, and metadata+
- Use grouped regex replacements and token patterns based on file name, extension, date, time, numbers, user, and folder.
- Insert EXIF date, GPS, camera, resolution, ID3 title, artist, album, track, and video metadata.
- Combine power tokens for substrings, CSV mapping, random strings, increment/decrement, and formatted values.
04Filters and file selection+
- Apply wildcard patterns or regex to names and process subfolders recursively.
- Limit path depth and minimum or maximum file-name and path lengths.
- Review the filtered file list with date, type, size, and sorting before building rules.
05Live preview and preflight+
- Compare original and result continuously and see status, conflicts, and invalid names per item.
- Search and filter large previews in pages and chunks with reduced memory use.
- Enable execution only after a valid preview and recheck source, target, and file state immediately before starting.
06Rename, copy, and move+
- Rename files in place, copy them to a target, or move them into a new structure within the same workflow.
- Block existing targets, preserve both with an automatic suffix, or overwrite deliberately.
- Reject or replace invalid characters, back up overwrite cases, and resolve swaps or cycles through two-phase renaming.
07Presets and recurring jobs+
- Save source, target, filters, mode, conflict strategy, performance options, and the complete rule chain as a preset.
- Mark favourites and immediately distinguish complete from incomplete presets.
- Apply presets by double-click and reuse them for photo imports, podcast exports, archives, or media collections.
08CLI and automation+
- Run saved presets through the included self-contained command-line tool.
- Override source and target, perform dry runs, and explicitly start unattended execution with execute/yes.
- Use JSON, quiet and verbose output, fail-on-skip, aliases, and defined exit codes for batch and CI scripts.
09JavaScript rules+
- Add custom JavaScript logic as a programmable step in any rule pipeline.
- Use a full editor with syntax highlighting, function navigation, ctx-field selection, debugging, and testing.
- Open token, regex, and JavaScript references directly from the modular rule editor.
10Undo, logs, and traceability+
- Undo every executed batch from persistently stored sessions and individual operations.
- Review the complete execution log, export it as CSV or JSON, and clear it inside the application.
- Overwrite backups, rollback logic, and retries protect undo operations from transient file errors.
11Performance and robustness+
- Scan files as a stream and process simple rule chains through an optimized fast path.
- Run copy and move operations with controlled parallelism, cancel long jobs, and retry I/O errors with backoff.
- Persist large logs in chunks, cache metadata, and safely lock shared roots across application processes.
Control instead of a black box
You see beforehand what happens afterwards.
Correcting an error in a single file is quick. With a thousand files, it’s a different story.
That is why the preview is one of the most important parts of rsk.rename for me.
You see the original and new filenames side by side. Conflicts become visible before you start the process. And the operation only begins once the result looks exactly the way you want it to.
Directly compare original and result → Detect conflicts before execution → Check first, then execute
rsk.rename organizes files far beyond renaming.
rsk.rename can also copy and move files. You can save recurring workflows as presets and reuse them later.
And if you want to automate a workflow, you can execute saved presets via the command line.
So you can start small.
And go pretty far, if you like.
For quick jobs
Drop in the files, create a rule, check the preview, and you’re done.
For recurring tasks
Save your settings as a preset and recall them next time.
For complex rules
Use placeholders, regular expressions, and custom JavaScript logic.
For automated processes
Execute prepared presets via the command line and integrate rsk.rename into existing workflows.
Try first. Decide afterwards.
Try it out with your own files.
The test version is there so that you can not only look at rsk.rename , but actually try it out.
For seven days, you can use every rsk.rename feature without file limits or locked functions.
That is perfectly sufficient for a first real workflow.
After the seven days, a valid license is mandatory to continue using rsk.rename.

Directly from the developer
I am developing rsk.rename myself.
Hi, I’m Christian.
The idea behind rsk.rename is quite simple: If a computer can reliably perform a task for me, I don’t want to do it by hand hundreds of times.
These are exactly the kind of tools I enjoy developing.
rsk.rename is designed to deliver quick results for simple tasks, yet not suddenly hit its limits when a job becomes somewhat more specialized.
If you have a question, find a bug, or have an idea for the application, you can write to me directly.
