Skip extension option is present in every rule. Its purpose is to eliminate extension of the filename from processing.
|File name||Extension||Base name|
|A Song.mp3||.mp3||A Song|
If skip extension options is used the rule will only be applied to the base name of the file.
Note: Extension is considered to be whatever follows the last dot in the filename. Prior to ReNamer v5.74.5 Beta a dot in the name of a folder was also considered to identify an extension, hence, this option also applied to folders. In newer versions the extension in folders is no longer treated as such, however, this behaviour can be changed in the Settings.
