Best Practices for Online File Renaming

Before Renaming

Backup Important Files: Always keep copies of original files before batch renaming.

Organize by Project: Group related files together for consistent naming.

Plan Naming Convention: Decide on naming patterns before starting (though AI tools like File Renamer AI handle this automatically).

During Renaming

Use Preview Mode: Always review suggested names before applying.

Check for Duplicates: Ensure no name conflicts exist.

Maintain Context: Good file names should be self-explanatory (e.g., "sunset-over-mountains.jpg" vs "IMG_5847.jpg").

After Renaming

Verify Results: Spot-check renamed files to ensure accuracy.

Organize Folders: Place renamed files in appropriate directories.

Update References: If files are linked elsewhere, update those references.
