Alphabetize

Alphabetize renames your selected files using sequential letters: A, B, C, and so on. It works like Auto Numbering, but uses letters instead of numbers.

How It Works

Select the files you want to rename in Windows Explorer.
Right-click and choose FilerFrog → Rename → Alphabetize.
Click OK to apply.

Each file is renamed to a letter in sequence — A, B, C, etc. — while keeping its original extension.

Example: You select three files — Filer.PDF, Document.PDF, and Report.PDF. After applying Alphabetize, they become A.PDF, B.PDF, and C.PDF.

What happens after Z?

When the sequence reaches Z, it wraps around and continues with double letters: AA, AB, AC, and so on. This means you can alphabetize any number of files without running out of names.

Alphabetize with Append

This variant adds a prefix and/or suffix around each letter, giving you more descriptive filenames while still maintaining alphabetical order.

Select files and choose FilerFrog → Rename → Alphabetize with Append.
Optionally enter a prefix and/or suffix.
Click OK to apply.

Example: With the prefix set to Chapter-, your files become Chapter-A.PDF, Chapter-B.PDF, Chapter-C.PDF, and so on.

Tip: Alphabetize is especially useful when you need a short, clean naming scheme for files that will be sorted alphabetically in a folder or archive.

Scenario

You are preparing a set of reference documents for a manual. Each document needs a simple letter identifier. Select all the documents, apply Alphabetize with the prefix Ref-, and you get Ref-A.docx, Ref-B.docx, Ref-C.docx — clean and easy to reference.

Lowercase Option

Check Use lowercase to generate lowercase letters (a, b, c...) instead of uppercase (A, B, C...).
