Install Bulk Rename Utility on Windows 11
Install BRU using an installer from the publisher and start with a disposable test directory before renaming important files.
Use Bulk Rename Utility without installing
The portable ZIP can run BRU from a folder without a typical setup procedure; extract it before starting.
First batch rename in Bulk Rename Utility
Select files, change one rule, inspect the New Name column, and apply the change only when every result is correct.
Bulk Rename Utility interface explained
The folder tree selects a location, the file list previews changes, and numbered panels control transformations in order.
Rename only selected files
BRU applies a rename to selected files; Ctrl and Shift can select subsets without affecting the whole directory.
Save and reuse BRU renaming favourites
Favourites preserve a set of renaming rules for repeat tasks, but a saved configuration still needs previewing on every new folder.
Reset renaming rules before a new job
Reset clears unintended active transformations so only the rules you choose will affect names.
Batch rename files on Windows 10
Bulk Rename Utility can handle complex file naming in Windows 10 with preview and rule panels not offered by basic Explorer rename.
Bulk Rename Utility vs Windows File Explorer rename
Explorer suits simple sequential names, while BRU exposes text replacement, filtering, metadata, regex and reusable configurations.
Find and replace text in hundreds of filenames
Use the Repl. panel to replace repeated words or symbols in the selected filenames without editing file contents.
Remove a word from multiple filenames
An empty replacement value removes the matched text from names while preserving other characters.
Add a prefix to many filenames
The Add panel can prepend the same project label to all selected file names.
Add a suffix before file extensions
The Add panel appends suffix text to the filename stem, before .jpg or another existing extension.
Insert characters in the middle of a filename
BRU can insert a separator or label at a specified position in a file name without replacing the full name.
Remove the first characters from filenames
The Remove panel strips a fixed count of leading characters from every selected filename.
Remove trailing characters before the extension
Use the Remove panel to trim unwanted characters from the end of the filename stem.
Remove digits from filenames in bulk
The Remove panel can delete numeric characters throughout a filename when IDs are no longer needed.
Remove special symbols from multiple filenames
The Remove symbols option is useful when punctuation breaks an upload convention or system integration.
Replace spaces with underscores in filenames
Replace spaces with underscores to create filenames suitable for scripts and predictable URLs.
Replace underscores with spaces in filenames
A simple replacement rule can restore readable spaces in filenames exported from scripts.
Clean repeated spaces in many filenames
Use text replacement iteratively to reduce doubled spaces between words.
Change filename case in bulk
The Case panel changes uppercase, lowercase or title-style filename text without changing file data.
Convert filenames to lowercase
Choose a lowercase filename transformation for consistent file naming, then preview extension handling separately.
Apply title case to a batch of filenames
A title-style case rule makes word-based filenames easier to read, but punctuation and abbreviations can need review.
Add sequential numbers to a group of files
The Numbering panel creates an ordered sequence for selected files, optionally with leading zeros.
Add leading zeros to filenames
Use numeric padding so alphabetical sorting matches intended numeric order.
Start filename numbering at a custom value
The Numbering panel can start at 100 or another value instead of one.
Number files in increments rather than one
Numbering can use a custom increment to leave gaps for future insertions.
Rename images in chronological sort order
Sort the file list by the relevant timestamp before assigning sequential numbers for archives.
Replace outdated numbering in filenames
Remove the old prefix or suffix first, then generate a new number range from the intended sort order.
Rename photos as 001, 002, 003
Apply a fixed base name with three-digit numbering to obtain consistent photo names.
Keep original names and append a sequence
Retain descriptive stems and append a numeric suffix to make duplicates distinguishable.
Add a date to filenames in bulk
Auto Date can insert a file date as a prefix or suffix using a consistent format.
Rename files using date modified
Use the file's last-modified timestamp when a content update should determine its output filename.
Rename photos by EXIF date taken
Use embedded camera date metadata for photo sequences rather than filesystem copy dates.
Add creation dates to file names
Bulk Rename Utility can use a filesystem creation-date field to label batches imported on Windows.
Add date and time to filenames
A timestamp suffix can reduce naming collisions when exporting repeated batches.
Reformat dates already written in filenames
Use regex groups to rearrange an existing filename date string without changing the file metadata.
Group photo names by year and month
Add year-month date text to a filename so media archives sort naturally.
Rename MP3s using ID3 artist and title tags
Read embedded ID3 fields to create consistent artist-title music filenames.
Add MP3 track numbers to filenames
Use track number tags to organize album filenames for alphabetical sorting.
Batch rename video files without changing formats
BRU changes video filenames and can use relevant properties, but renaming does not transcode the video.
Bulk rename JPG and JPEG photos
Filter JPG and JPEG files before applying a descriptive naming scheme.
Rename PDF files in a folder
BRU can rename PDFs by filename patterns; embedded document metadata may require additional components.
Batch rename CSV and Excel exports
Standardize spreadsheet export filenames while keeping workbook contents untouched.
Rename files using a CSV mapping list
Use a prepared old-name/new-name mapping where supported rather than guessing names from generic patterns.
Add image dimensions to filenames
Where supported property tags exist, include width and height so asset variants remain distinguishable.
Bulk rename folders in Windows
BRU can rename directories as well as files, but folder operations may affect applications storing paths.
Rename files recursively across subfolders
Enable the subfolder option to apply filename rules to nested directories while preserving folder structure.
Include parent folder names in filenames
Append Folder Name can distinguish identical filenames that originate in separate project directories.
Move renamed files to a new directory
When using New Location, confirm the destination path and potential collisions separately from filename transformations.
Rename directory names without touching contained files
Filter to folders only before applying a directory naming rule.
Rename files but leave directory names unchanged
The Files-only selection is safer for a batch where folder structure must remain fixed.
Filter and rename several extension types
Use extension filters to restrict a job to documents, photos or videos before applying transformations.
Exclude hidden and system files from a batch
Review Hidden and Files/Folders filter options before renaming a directory that contains technical files.
Use wildcards to target filenames
A wildcard filter limits which filenames are eligible for renaming, even in a mixed folder.
Beginner regex tutorial for Bulk Rename Utility
Use regular expressions when a filename pattern has multiple parts that simpler replacement cannot isolate.
Swap two filename sections with regex
Capture both filename sections and reverse their order with a regex replacement.
Remove parentheses and their contents with regex
A regex can strip a bracketed copy label when it is present, keeping the original filename stem.
Extract numeric IDs from mixed filenames
Capture a numeric field and rearrange it into a predictable naming convention.
Strip a variable filename prefix using regex
A regex handles prefixes of variable length when they share a reliable separator.
Rearrange filename dates with capturing groups
Capture day, month and year separately to convert names into sortable ISO dates.
Remove repeated filename words with regex
A regex backreference may detect a repeated word and collapse it to one occurrence.
Protect extensions while running regex rules
Use a filename-only match and leave the Extension panel unchanged so the file format label stays intact.
When to use regex instead of simple replace
Choose literal replacement for a known text string and regex when structure, optional components or capture groups matter.
Use JavaScript in Bulk Rename Utility v4
Version 4 supports JavaScript rules for transformations too complex for fixed controls; test scripts on disposable copies.
Preview file renames before applying
The New Name column is a safety check showing expected changes before any filesystem operation.
Undo a bulk rename operation
BRU offers mechanisms for reverting some recent renames, but recovery should be tested before a large or critical batch.
Prevent duplicate filenames during batch rename
A batch must produce unique target names in the same directory to avoid conflicts.
Create a backup before renaming 1000 files
Keep a verified copy or versioned backup before a batch that affects many files or nested directories.
Test a renaming rule on three sample files
A small rehearsal exposes unexpected case changes, extension modifications and duplicate results early.
Keep file extensions unchanged
Most BRU name transformations change the filename stem; leave Extension rules inactive to preserve the recognized type.
Fix Access Denied errors when renaming files
Access Denied may arise from permissions, open handles or protected locations rather than a broken renaming rule.
Rename files locked by another process
Windows can block a rename while a file is open; close the application holding it rather than forcing an operation.
Avoid invalid characters in Windows filenames
Windows forbids characters such as colon, question mark and backslash in ordinary filenames.
Troubleshoot very long Windows filenames
Deep directory paths may exceed limits for some applications even when the naming rule itself works.
Batch rename files on a network share
Renaming on a shared drive can disrupt other users and requires permission and conflict checks.
Rename OneDrive-synced files safely
Renaming a synced folder can trigger large sync updates and break shared links or references.
Filename changes do not convert file formats
Changing .jpg to .png in a filename does not transform the actual image data.
Handle read-only files during batch rename
Read-only attributes and parent-folder permissions can affect whether a batch rename succeeds.
Bulk Rename Utility vs PowerToys PowerRename
BRU has extensive rule panels and metadata workflows; PowerRename integrates into Microsoft PowerToys and is often easier for simple patterns.
Bulk Rename Utility vs Advanced Renamer
Both applications offer batch renaming; compare the exact features and licensing needed rather than assuming identical behavior.
How to choose a Windows batch renaming tool
Choose based on pattern complexity, preview safety, metadata support, file count and licensing conditions.
Bulk Rename Utility free vs commercial licensing
The publisher describes BRU as free for personal private use at home, with a commercial license required for business use.
PowerShell Rename-Item vs Bulk Rename Utility
