How to Rename Multiple Folders in Windows with Easy System Utility PRO

Renaming folders one at a time can take a while when you are organising photographs, projects, customer files, backups or other large collections.

The Rename Folders tool in Easy System Utility PRO lets you add several folders to one list and rename them together using the same settings. You can keep each folder’s original name, add custom text and include sequential numbers to create a clearer and more consistent folder structure.

Rename Folders is a PRO feature because it is designed specifically for bulk folder renaming.

When is bulk folder renaming useful?

Bulk renaming can help when folders have inconsistent, unclear or automatically generated names.

For example, you might have folders named:

• New Folder
• New Folder (2)
• New Folder (3)
• Photos1
• Photos2
• Photos3

You could rename them into a more organised sequence such as:

• Holiday Photos 01
• Holiday Photos 02
• Holiday Photos 03

The tool can also be useful for:

• Photograph collections
• Customer or client folders
• Website projects
• Monthly reports
• Product images
• Property photographs
• Music collections
• Video projects
• Backups
• Scanned documents
• Course or training folders
• Archived work

Using a consistent naming pattern makes folders easier to sort, search and recognise later.

Rename Folders is included with PRO

The bulk Rename Folders tool requires Easy System Utility PRO.

PRO lets you add multiple folder paths, configure the naming format and process the complete list together.

This saves time compared with manually renaming every folder through Windows File Explorer.

The tool is especially useful when the folders should follow the same naming structure.

How to open Rename Folders

To access the tool:

1. Open Easy System Utility.
2. Select Folders and Files from the left-hand menu.
3. Open the Rename Folders tab.
4. Add the folders you want to rename.
5. Review the folder list.
6. Configure the new naming format.
7. Preview the intended structure where possible.
8. Start the rename process.

Before beginning, check that Easy System Utility PRO is activated.

Add folders to the rename list

Use the folder selection controls to add each folder you want to rename.

You can build a list containing several folders before applying the new naming settings.

As you add them, check the complete folder paths carefully.

Folders with similar names may exist in different locations, particularly inside:

• Documents
• Pictures
• Desktop
• OneDrive
• External drives
• Project directories
• User profile folders

Only add the folders that should follow the same renaming pattern.

Review the folder order

When sequential numbers are being added, the order of the folders can affect which number each one receives.

For example, the first folder may become:

Project 01

The second may become:

Project 02

The third may become:

Project 03

Before renaming, check that the folders appear in the order you want.

A folder receiving the wrong number may not cause a technical problem, but it can make the final organisation confusing.

When the order is important, consider renaming smaller groups rather than adding hundreds of folders at once.

Keep the original folder name

Easy System Utility PRO can preserve the original folder name as part of the new result.

This is useful when the existing names contain important information but need extra text or numbering.

For example:

Original folders:

• London
• Bristol
• Manchester

You could retain the original names and add a prefix:

• Customer Photos - London
• Customer Photos - Bristol
• Customer Photos - Manchester

Or add a number:

• 01 - London
• 02 - Bristol
• 03 - Manchester

Keeping the original name reduces the risk of losing useful information while still making the folders more consistent.

Replace the original folder name

When the existing folder names are not useful, you can create a new shared name for the complete group.

For example:

• New Folder
• Untitled
• Folder Copy

could become:

• Event Photos 01
• Event Photos 02
• Event Photos 03

This works best when the folders belong to the same project or category.

Be careful when replacing names that contain dates, customer details or other information you may need later.

Once the original name has been replaced, it may be difficult to remember which folder previously contained which information.

Add text before the folder name

Adding text before the existing name creates a prefix.

For example:

Original:

January

With the prefix Invoices - :

Invoices - January

Other examples include:

• Client - Smith
• Project - Website
• Photos - Garden
• Archive - 2025
• Completed - Report

Prefixes are useful when Windows should group related folders together alphabetically.

Add text after the folder name

Text can also be added after the original folder name.

For example:

Original:

January

With the text - Complete:

January - Complete

This can be useful for adding:

• A year
• A project status
• A location
• A client name
• A file type description
• An archive label

Examples include:

• Accounts - 2026
• Website Images - Edited
• Customer Documents - Complete
• Project Alpha - Archive

Keep the additional text reasonably short so folder names remain easy to read.

Add sequential numbers

Numbers help keep folders in a clear order.

Without leading zeros, Windows may display folders in an unexpected order when there are more than nine items.

For example:

• Photo 1
• Photo 10
• Photo 11
• Photo 2

Using leading zeros produces a cleaner sequence:

• Photo 01
• Photo 02
• Photo 03
• Photo 10

For larger collections, you may need three digits:

• Project 001
• Project 002
• Project 003

Choose a numbering format large enough for the number of folders you plan to create.

Place numbers before or after the name

The best position depends on how you want the folders sorted.

Number before the name

Examples:

• 01 - January
• 02 - February
• 03 - March

This keeps the folders in a fixed sequence even when their names are different.

It is useful for:

• Instructions
• Courses
• Project stages
• Monthly records
• Ordered archives
• Event schedules

Number after the name

Examples:

• Holiday Photos 01
• Holiday Photos 02
• Holiday Photos 03

This works well when every folder uses the same shared name.

It keeps the description at the beginning while the number separates each folder.

Use separators to make names readable

Separators make folder names easier to understand.

Common choices include:

• Spaces
• Hyphens
• Underscores
• Brackets

For example:

• 01 - Customer Photos
• Customer_Photos_01
• Website Images (01)
• Project - Completed

Avoid placing words and numbers directly together unless that is the style you want.

For example, Project01 may be less readable than Project 01.

Check for invalid Windows characters

Windows does not allow certain characters in folder names.

Avoid using:

< > : " / \ | ? *

These characters have special meanings in Windows and can prevent a folder from being renamed.

A normal folder name can safely use letters, numbers, spaces, hyphens, underscores and brackets.

If a rename fails, check the custom text for unsupported characters.

Avoid excessively long folder names

Windows supports long paths, but some programs still have difficulty with very long folder and file paths.

Remember that the complete path includes:

• The drive letter
• Every parent folder
• The renamed folder
• Any folders and files inside it

For example:

C:\Users\Name\Documents\Customer Projects\Very Long Project Name\Another Folder\

Adding a large amount of extra text can make the full path unnecessarily long.

Keep folder names descriptive but reasonably concise.

Check whether another folder already uses the name

Two folders inside the same parent folder cannot have exactly the same name.

For example, if this folder already exists:

C:\Photos\Holiday Photos 01

another folder in C:\Photos cannot be given the same name.

A conflict may occur when:

• The numbering starts at the wrong value
• A previous rename already created the name
• The original folder is still present
• Two folders are being given identical custom names
• Numbering has not been enabled

Review the destination folder through File Explorer before starting a large rename.

Close programs using the folders

A folder may not rename successfully when it is being used by another program.

Before beginning:

• Close files stored inside the folders
• Close image or video editors using them
• Stop any active copying or moving process
• Close command windows opened at those paths
• Pause software that is actively writing to the folders
• Close File Explorer preview panes where necessary

Cloud storage services may also be synchronising the folders.

Allow the sync to finish before renaming them.

Be careful with cloud storage folders

Folders stored in OneDrive, Dropbox, Google Drive or another cloud service may be renamed both locally and online.

This can affect:

• Shared links
• Synced computers
• Automated workflows
• Collaborators
• Backup software
• Shortcuts
• Recently used file lists

Make sure the folders are fully synchronised before renaming them.

After the process, allow the cloud service time to upload the name changes before shutting down the computer.

Folder renaming can affect shortcuts

Programs and shortcuts may refer to a folder using its complete path.

If the folder name changes, an existing shortcut may continue pointing to the old location.

You may need to update:

• Desktop shortcuts
• Program settings
• Backup jobs
• Script paths
• Website project settings
• Recent folder links
• File synchronisation rules
• Media library locations

Only rename program or project folders when you understand what may depend on their existing path.

Avoid renaming Windows and program folders

Do not use the bulk rename tool on major Windows or application folders.

Avoid locations such as:

• C:\Windows
• C:\Windows\System32
• C:\Program Files
• C:\Program Files (x86)
• Application data folders
• Driver folders
• Recovery partitions

Changing these names could stop Windows or installed software from finding required files.

Rename personal, project and storage folders instead.

Be careful with folders containing installed software

Portable applications may run directly from a normal folder, while other programs may store configuration files using their folder path.

Renaming the folder could break:

• Program shortcuts
• Update systems
• Saved settings
• Plugins
• Linked files
• Launchers
• Scheduled tasks

Check whether the folder is simply storing files or is actively used by installed software.

Back up important folder structures

Renaming normally changes the folder name rather than the contents, but it can still affect anything that relies on the previous path.

Before renaming important folders:

1. Back up essential files.
2. Record the current folder names.
3. Save a screenshot of the existing structure.
4. Close related programs.
5. Rename a small test group first.
6. Check that the files still open normally.
7. Continue with the remaining folders.

This is particularly useful for business records, project archives and large photo collections.

Rename a small group first

When using a new naming format, test it on two or three folders before processing the complete collection.

This helps you check:

• Text placement
• Number formatting
• Spacing
• Folder order
• Whether original names are preserved
• Whether any program depends on the old paths

A small test is easier to correct than hundreds of folders with an unsuitable naming pattern.

Remove a folder from the list

If a folder was added by mistake, remove it from the rename list before starting.

Removing it from the Easy System Utility list does not delete or rename the folder. It only prevents it from being included in that bulk operation.

Check the complete list one final time before selecting the rename button.

Clear the folder list

Use the clear option when you want to remove every entry and begin again.

This is useful when:

• The wrong parent folder was selected
• The folders are in the wrong order
• You want to create separate groups
• You have changed the naming plan
• The list contains a mixture of unrelated folders

Clearing the list does not affect the actual folders stored on the drive.

Why could a folder not be renamed?

A folder may remain unchanged when:

• It is in use by another program
• A file inside it is open
• Another folder already has the proposed name
• The new name contains invalid characters
• The path is too long
• Windows permissions block the change
• The drive is read-only
• Security software is protecting the folder
• The folder was moved after being added
• A cloud service is currently processing it

Check the folder and new name, then try again.

Run Easy System Utility as an administrator

Some folders require additional Windows permission before their names can be changed.

To run the tool with administrator access:

1. Select Start ESU as administrator.
2. Approve the Windows User Account Control prompt.
3. Return to Folders and Files.
4. Open Rename Folders.
5. Add the folders again if necessary.
6. Repeat the rename process.

Administrator permission may help with restricted folders, but it does not make Windows system folders suitable for renaming.

What happens to files inside a renamed folder?

Renaming a folder does not normally rename or change the files inside it.

The folder’s contents stay together under the new path.

For example:

Original:

C:\Pictures\New Folder\photo.jpg

After renaming the folder:

C:\Pictures\Holiday Photos\photo.jpg

The filename remains photo.jpg, but its complete path changes because the parent folder now has a different name.

Any program looking for the old path may need to be updated.

Can renamed folders be changed again?

Yes. You can rename the folders again through Easy System Utility or Windows File Explorer.

However, the tool may not automatically know the names they had before the previous operation.

If you completely replace the original names, keep a record of them until you are satisfied with the result.

Preserving the original folder name as part of the new format can make changes easier to understand and reverse manually.

A sensible bulk folder renaming process

A careful way to rename multiple folders is:

1. Decide on a clear naming format.
2. Back up important files.
3. Close programs using the folders.
4. Open Folders and Files > Rename Folders.
5. Add the required folders.
6. Check their full paths.
7. Arrange or review their order.
8. Decide whether to preserve the original names.
9. Add any custom text.
10. Configure sequential numbering where required.
11. Check for invalid characters.
12. Test the format on a small group.
13. Start the rename process.
14. Review the completed folder names in File Explorer.
15. Update shortcuts or program settings that used the old paths.

Easy System Utility PRO makes it quicker to rename multiple folders using a consistent structure. By preserving useful names, adding clear descriptions and creating numbered sequences, you can organise large folder collections without repeating the same manual steps in Windows File Explorer.
