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 video files 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) |
|---|---|
camera0001.mp4 | Project-001.mp4 |
How to do it step by step
- Step 1. Choose the video directory.
- Step 2. Select files with supported extensions.
- Step 3. Apply a consistent prefix or number.
- Step 4. Confirm extensions are unchanged.
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 video files in Bulk Rename Utility?
BRU changes video filenames and can use relevant properties, but renaming does not transcode the video.
What should I check before applying this batch?
Compare the New Name preview for every selected file, check for duplicates and verify extensions. Changing .mov to .mp4 in the name does not convert the video format.
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.
