Replace occurances of a user defined string s1 with a user defined string s2. If s2 is empty, occurances of s1 will be stripped (removed).

Replace string s2 may contain formatting parameters, which will be parsed and used by the replacer.

• "Match case": when checked, only strings with exact case as of s1 will be replaced.
• "Replace only first occurance": when checked, only first occurance of s1 in each filename will be replaced.
• "Replace only whole words": when checked, occurances of s1 which forms a word will be replaced.
  Words are seperated by the the default space character, which can be changed by adding the Space Char filter to the apply list before this filter.
• "Search string is a regular expression": Replacer will treat s1 as a regular expression. In this case, s2 may contain the expression $0, which will be parsed to the string matched to the regular expression.
  When this ooption is checked, the options "Replace only whole words" and "Match case" cannot be used.

Examples

Replace 'dog' with 'cat', replace only whole words:

The dogs ran from the dog.txt    >>>   The dogs ran from the cat.txt

Replace '[0-9]*' with '[$0]', replace only first occurance, search string is a regular expression:

06 - Trouble.mp3   >>>   [06] - Trouble.mp3
