Frequently Asked Questions

Common questions about Clean Filenames

No. The plugin does its job just after a file is uploaded and before it's saved to your server, so it'll change only filenames for files being uploaded after plugin activation.

Since 1.2.2 version, you can use the scf_friendly_filename filter to perform additional changes to the filename after all the changes done by the plugin. Example: add_filter ('scf_friendly_filename', 'first_character_uppercase', 10, 1); function first_character_uppercase ( $friendly_filename ){ // Make sure first character is always uppercase. $friendly_filename = ucfirst( $friendly_filename ); return $friendly_filename; }

Probably. Simply give it a try and see how it goes. This plugin doesn't store anything in your site or anywhere, and makes no permanent changes to the site, disabling the plugin is enough to go back to WP default filename handling. Therefore trying and uninstalling the plugin if it doesn't fit your needs it's a completely safe and clean task.
