How to use?

Renaming has the following 3 steps in Smart Bulk Renamer.

  1. Pick files
  2. Apply rules & preview modified names
  3. Rename

1. Pick files

Smart Bulk renamer supports both cloud and local file renaming. Both the types let you pick multiple files or folders for renaming.

When you pick folders, you will rename the files inside those folders. Smart Bulk Renamer doesn't support renaming folders yet.

Cloud

For now, Google Drive, Dropbox & OneDrive file renaming is supported.

When you select one of the cloud options, first your need to authenticate & authorize access to your files by clicking on the Pick from button. Then, a file picker opens where you can pick multiple folders or files for renaming.

It is recommended to pick folders instead of multiple files as it reduces the number of API calls required to fetch files which speeds up the process.

When the picked folder has more than 500 files, the tool stops fetching all the files and lists approximately 500 files. But, when it starts renaming it will apply the renaming rules to all the files inside that folder. You will also see an alert regarding this.

Local

You can rename local files only on Chromium-based browsers like Chrome, Microsoft Edge or Opera on a PC or Mac due to the unavailability of certain APIs on other browsers. Mobile & iPad or not supported.

Select Local Disk at the top of this page. Now, select one of Pick a folder or Pick files and select a folder/files to continue with the renaming.

2. Apply rules & preview modified names

After picking, appropriate files are fetched. Once the files are fetched, you should see a table like the one shown below. Files are listed under a folder path. You can collapse the files under a folder simply by clicking on it.

You will see a form similar to the one below to the right of the file list. This is where you set the rules for file renaming.

Before we know about these types in detail, there are 3 concepts you should know beforehand. You will find at least one or all available to all of the renaming types.

Preserve extension

When this is checked, the extension of the file is left intact. The renaming rule is only applied on the file name. When this is unchecked, the extension is forgotten.

Let's consider the file dino.png when you add suffix saur,

Ignore files in nested folders

When this is checked, only the files directly inside the picked folder(s) are considered for renaming.

Consider the example below, here, the folder selected is My Wedding and the files are renamed to have their sizes. When we check Ignore files inside nested folders, only the files directly inside My Wedding folder are considered for renaming. Other files are ignored.

i. Find and Replace

You can query for a particular text in the file name and replace with someother text you want. When quering for text, you can choose to ignore the case of your query text and/or use regular expressions.

When using regular expressions to target files based on their extensions, remember to uncheck Preserve extension to get the desired results.

ii. Sequence

Renames your files in a numbered sequence. You can set the starting number of the sequence, sequence incrementor and the number of digits a number in sequence should have.

Sequence renaming has a 3 valid Group by options: No grouping, Parent folder, Content type.

No grouping

All files are renamed in one sequence.

Parent folder

Every folder has its own sequence or the sequence is restarted whenever a new folder is found.

Content type

Every unique file type has its own sequence. For example, regardless of the parent folder all png files are renamed in one sequence. pdf files will have a separate sequence and so on.

iii. Compose

You can compose a new file name from scratch using this option. You should choose metadata to keep the names of files unique.

iv. Add Prefix

Helps to add prefixes to the file names.

v. Add Suffix

Adds a suffix to the file names.

vi. Insert

You can insert a piece of text at a set position in your file name. You can count the position from the start or end of the file name with a config.

vii. Remove

You can remove a set number of characters from a set position in your file name.

viii. Change Case

You can change the case of your file name and/or its extension. Supported cases: lower, upper, title & capitalized.

ix. Set Extension

Sets extension for the file names. You can enable a config to only set extensions for the files that already have an extension.

3. Rename

After you set the rules and verify the file name changes in the preview, select Rename files. You will see a modal with a warning stating, This action is irreversible. Once you are sure, select Yes, rename files to rename your files.

Sometimes, when duplicate names are in the same folder or file names start with a dot, you might see more alerts before renaming. How such cases are handled is based on the source of the files.

You will see the renaming progress after it starts.
