Truncation Actions
Shorten file names to a fixed length while keeping the extension, or to DOS 8.3 format: the Truncation actions of Better Rename.
The Truncation category shortens names to a fixed length.
Truncatecuts the name after the number of characters inTruncate to:.

Truncating often gives several files the same name. Automatic conflict resolution
then numbers them, and Preview Conflict Resolution in the View › Preview menu shows the result.
Example
Scans were saved with the whole first line of the document as their name, e.g.
Minutes of the annual general meeting held on 14 October 2026 in the town hall.pdf, and a backup program refuses
names longer than 40 characters.

The name becomes Minutes of the annual general meeting he.pdf: 40 characters, then the untouched extension. If two
scans start with the same 40 characters, the preview shows the conflict and the numbers that resolve it.
