Bulk Rename Utility lets you set rules separately, select the exact items to be affected, and preview the results in a New Name column. The workflow below focuses on bulk rename utility vs powerrename without changing unrelated files.
Example: before and after
These filenames are examples to explain the transformation; they are not test results from your files.
| Before | After (illustrative) |
|---|---|
replace names in a folder | same target names, different workflows |
How to do it step by step
- Step 1. List the naming transformations needed.
- Step 2. Try a three-file sample in both tools.
- Step 3. Compare preview and rollback options.
- Step 4. Choose the tool that handles your metadata and recursion needs.
Why this workflow works
The rule and selection work together: the rule changes eligible filenames, while the selection limits which files receive the change. Always inspect the New Name column and confirm the directory before choosing Rename. For repetitive work, save verified settings as a favourite, but review them again on each new batch.
How to verify the results
Compare the original and proposed filenames side by side, check that each target name is unique in its directory, and confirm file extensions match the actual file types. After applying the rule, open a sample file in its usual Windows application and check any shortcuts or scripts that use the old path.
Frequently asked questions
How do I utility vs powerrename in Bulk Rename Utility?
BRU has extensive rule panels and metadata workflows; PowerRename integrates into Microsoft PowerToys and is often easier for simple patterns.
What should I check before applying this batch?
Compare the New Name preview for every selected file, check for duplicates and verify extensions. The tools have different regex syntax, filtering and installation requirements.
Does changing a filename also change its contents?
No. A standard filename rename changes the name or path, not the document, photo, audio, or video data. Changing an extension also does not convert a file format.
