Truncate

Truncate removes a specified number of characters from the beginning or end of filenames. It is a fast way to strip unwanted prefixes, suffixes, or extra characters that clutter your file names.

How It Works

  1. Select one or more files in Windows Explorer.
  2. Right-click and choose FilerFrog → Rename → Truncate.
  3. Enter the number of characters to remove.
  4. Choose whether to remove characters from the beginning or end of the filename.
  5. Click OK to apply.
Example: You have a file named 01-Song1.mp3. Set the truncation to remove 3 characters from the beginning. The file is renamed to Song1.mp3 (the 01- prefix is removed).

Options

Example (from end): A file named Report_DRAFT.docx with 6 characters truncated from the end becomes Report.docx (the _DRAFT suffix is removed).
Tip: Truncate is especially handy when dealing with files exported from tools that prepend or append codes, timestamps, or tracking numbers to filenames.
Scenario

You ripped tracks from a CD and each filename starts with a track number like 01-, 02-, etc. Select all the files, set truncation to 3 characters from the beginning, and the track number prefixes are stripped from every file in one step.

Keep First N Characters

Switch to Keep first characters mode to keep only the first N characters of each filename, removing everything after.

Example: "VeryLongDocumentName.pdf" with Keep first 8 → "VeryLong.pdf"
