Specify the target file

You can specify the target file to be renamed in two ways: "File Search" or "Direct Specification".

To remove a file from the target file list, click the button on the left side of the line. You can also empty the file list by clicking the upper left button.

File Search

Search for files in any folder and add them to the target file list.

There are three ways to search for files:

• Select from the folder icon in the upper left corner using the dialog.
• Dragging a folder to the folder path in the upper left corner.
• Directly enter the folder path in the upper left corner and press the File Search button.

You can specify the conditions for file search from Rules > File Search.

Directly specify

Directly specify the files to be renamed.

There are two ways to specify directly:

• Use the Add Files dialog above to select the file.
• Drag the file to the file list.

Rename settings

Specify the conditions for file renaming.

The execution order of the conditions is "Delete" → "Replace". If you want to delete the file after "Replace", leave Replace Text empty in Replace Pattern, which is the same as "Delete".

Delete Texts

Specify the characters to be deleted.

ADD adds a new line. You can delete a line by clicking the button on the right side of the line. To change the order of the lines, grab the left edge of the line and drag.

You can select the "Common Pattern" by clicking the bottom right button.

If the Regular Expression checkbox is checked, you can specify the characters to be deleted using regular expression.

Regular Expression

The regular expressions(Regex) in this software use "Microsoft .NET" regular expressions. The following is a list of typical ones. For a more detailed explanation, please refer to the following links.

Replace Pattern

Specifies the pattern before and after the replacement.

ADD will add a new line. You can delete a row by clicking the right button in the row. To change the order of the lines, grab the left edge of the line and drag.

You can select the "Common Pattern" by clicking the bottom right button.

If Regular Expression is checked, you can specify the replacement pattern using regular expression.

Regular Expression

The regular expression before replacement is the same as Delete Texts.

There are also regular expression that can be used after the replacement. Some of the most common are listed below. For a more detailed explanation, please refer to the following links

Substitutions In Regular Expressions - Microsoft Docs

File Renamer Original Regex

This is a regular expression unique to this application that is not found in the "Microsoft .NET".

Add special characters

You can add special characters by specifying symbols in Replace Text in Replace Patterns.

Add Serial Number dialog

Setting up serial numbers is complicated, so a settings dialog is available.

You can change the following settings and check them in the sample file list:

• Insert Position
• Start Number
• Step
• Zero-Padding Digits
• Reset per Folder
• Inverse
• Prefix Text
• Postfix Text

Finally, you can add to the Replace Patterns with ADD.

Rename confirmation

DRY RUN allows you to see the files before and after they are renamed.

The description of each column in the file list is as follows:

Save rename

SAVE will rename the actual file. Cannot be executed if there are duplicates in the file list.

If the directory to which the file belongs is rewritten when renaming is executed, it will be removed from the file list.
