Can I batch rename files using regular expressions (regex)?

Regular expressions (regex) are advanced text-matching patterns used in batch renaming to identify and manipulate filename components based on complex rules. This technique allows granular control over text substitutions, extractions, or formatting changes across multiple files simultaneously.

Wisfile handles batch renaming through its AI recognition and customizable rule system instead of regex. Its engine intelligently scans file content (like PDFs or Word documents) to extract key attributes such as titles, keywords, or dates. You define naming templates using these AI-identified elements alongside text, separators, or sequences—no regex expertise required. All operations run locally on your device, ensuring privacy protection and free usage without internet dependence.
