  Click the checkbox or file name (if you turned off checkboxes) to select the first one and Shift+Click the last one

  💡 You can change the User Interface via Settings > UI > Show Checkboxes

• Keyboard

  Use Tab and arrow keys to navigate to the item, Space to select, then hold Shift+Down to select downwards or Up to select upwards Hit Enter to directly enter inline-edit mode

Preview Panel Interactions

• Select the file name - For text, it’ll be the text to replace or move; for section, it’ll set the section’s start and length
• Double-click the file name - (Only when Replace/Move Text) Select the word and populate into the input
• Right-click the file name - Set the From position in Range

Operations

• Replace - Replace text or section, re-sequence, re-format date. Example: rename IMG_001.jpg → Photo_001.jpg by replacing IMG_ with Photo_
• Insert - Insert text or sequence. Example: add a 2024_ prefix to all selected files
• Move - Move text / section / sequence / date within the file name. Example: move a trailing sequence number from the end to the front
• Preset - Replace using preset rules such as clean up, changing to upper/lower cases. Example: strip illegal characters, or convert all names to lowercase

💡 Renaming can be done in multiple steps combining those operations. Undo or redo if the results are not satisfactory.

Parameters

Range

Range defines the segment of the file name that you would like to manipulate.

• From - the start position of the range (starting from 0 by default)

  💡 Right-click the file name in the Preview pane to populate the From value.

• Length - the length of a section, default Full

  💡 Selecting a section of the file name in the Preview pane will populate the value for you.

• Forward (default) - from the beginning, select forward (left-to-right)

• Backward - from the beginning, select backward (right-to-left)

💡 Clicking Range/Section resets the values to default

Types

Text

Replace / Insert / Move text.

💡 (Advanced) Input will be treated as Regexp if the text starts with /, e.g. /^a. Don’t put /gi in the Regexp - choose All for /g and Case-insensitive for /i

Section

Replace / Move a fixed-length segment.

Sequence

Insert / Delete / Replace a sequence.

Parameters:

• Digits

  Minimum sequence digits. E.g. Digits is 3, then sequence 1 will be padded with 0 as 001. When Digits is 0, it means to DELETE the sequence found. In Insert operation, Digits is always greater than 0.

• Step

  The increment / decrement step of the start number. E.g. Start is 1, Step is 2, then the sequence will be 1, 3, 5… When Step is 0 in Re-Sequence, it means to adjust the sequence digits only.

  E.g. existing sequence in file names is 1, 2, 3…, and Digits is 3, Step is 0, then the new sequence will be 001, 002, 003…

• Start

  The starting value of the sequence.

Date

Find date elements in file names and reformat them.

• Current Format Auto Detect should work most of the time. However, you can choose from the dropdown list if ambiguous.

• With New Format The new year/month/day format

• Year 4 digits / 2 digits / no year

• Month 2 digits (MM) / 3-letter abbreviation (e.g., Aug) MMM / full (MMMM) / no month

• Date 2 digits (with leading 0 if necessary) / 1 digit (no leading 0)

• Delimiter - . _ ,(Space)

⚠️ Currently Date type only supports English locale.

Batch Renaming Using a CSV File

In some cases, you may find it convenient to define a comma- or tab-delimited file for batch renaming.

Switch to CSV Mode

At the right bottom of the footer, you can choose between Interactive (default) or CSV modes.

CSV Format

The file needs two columns and no header line:

Current File Name, New File Name
...

⚠️ DO NOT put a header line.

For example:

a.txt,x.txt
b.txt,y.txt
c.txt,z.txt

Delimiters

, ; | (space) (tab) are automatically recognized. You can also specify your own delimiter if needed:
