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 number by date without changing unrelated files.
Example: before and after
These filenames are examples to explain the transformation; they are not test results from your files.

How to do it step by step
- Step 1. Check the timestamp source.
- Step 2. Sort the selected files ascending.
- Step 3. Enable the numbering rule.
- Step 4. Preview first and last results.
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 number by date in Bulk Rename Utility?
Sort the file list by the relevant timestamp before assigning sequential numbers for archives.
What should I check before applying this batch?
Compare the New Name preview for every selected file, check for duplicates and verify extensions. Explorer date fields, EXIF date taken and modified dates can differ.
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.
