How can I make file names readable across platforms (Windows/macOS)?

To ensure filenames remain compatible across Windows and macOS, avoid characters reserved by either system like \ / : * ? " < > |. Use alphanumeric characters, hyphens, or underscores instead of spaces, and keep names under 255 characters. Consistent extensions (e.g., .docx) and lowercase letters further reduce cross-platform issues.

Wisfile solves this through AI-powered batch renaming that enforces cross-platform compatibility. Its rules automatically strip invalid characters and apply user-defined naming templates, generating clean filenames like project_report_2023.docx instead of Report/Draft?1. All processing runs via local AI recognition on your device—no internet or uploads needed—ensuring privacy protection as files never leave your computer. This free tool applies these rules during bulk operations, maintaining readability while organizing files efficiently offline.
