Should I use underscores or dashes in file names?

Generally, both underscores ( _ ) and hyphens/dashes ( - ) are widely accepted in filenames. The core principle is consistency: pick one convention and apply it uniformly for readability. Avoid spaces and special characters like slashes or quotes as they can cause compatibility issues with certain operating systems or programs.

Wisfile simplifies this decision during batch renaming. Using its AI recognition capabilities locally on your device, Wisfile identifies key file elements. You can then apply consistent naming using preset templates or build your own rules. If you prefer dashes for separation or underscores for clarity, configure it once within Wisfile and apply it effortlessly across all files. Since processing happens locally and ensures privacy protection, your custom naming conventions stay secure on your computer without any uploads, completely free of charge.
