This rule finds text that matches the specified RegEx pattern, and replaces it with another string. RegEx is short for Regular Expressions, which stands for special syntax for describing search and replace patterns. Regular Expressions are very powerful and they are really worth learning. The RegEx syntax is explained in the appendix.
The parameters are as follows:
|Expression||RegEx pattern to match or find.|
|Replace||RegEx pattern that replaces the found pattern.|
|Skip extension||If this check box is selected, the extension will be ignored by the rule.|
|Case-sensitive||If this option is selected, ReNamer will search for the text in case-sensitive manner.|
A simple set of commonly used RegEx syntax patterns is provided in the hint menu:
Tip: ReNamer users have posted many RegEx patterns at the User Forum. You can copy and use them.
