Replace Rule

ReplaceRule.png

This rule removes the specified string from the name and replaces it with another string. It has options to replace the first occurrence, the last occurrence, or all the occurrences. You can replace multiple strings at a time. You can create a pattern with wildcards, so that any string that matches the pattern will be removed.

The parameters are as follows:

Parameter Details
Find Enter the string to be replaced.
  • You can enter multiple strings at a time. They will be searched & replaced in the order as they appear. Press the + button to insert a separator between two strings. Instead of pressing this button, you can also enter *|* from the keyboard.
  • If the name does not contain the specified string, the rule will not act on it.
  • If the name contains more than one of these strings, it will replace them according to the Occurrences parameter.
PlusButton.png button Inserts a separator (*|*) sequence between two delimiter entries. (You can directly type*|*

You can use this button in the Replace box also. In that case, the nthe entry in the Find box is replaced by the nths entry in the Replace box. (e.g. A -->A', B -->B' etc.) }

Replace Enter strings that will replace the "Find" strings.
  • Note that the number of strings (separated with *|*) in "Find" and "Replace" boxes should be the same. If there is more strings in the "Find" box than in the "Replace" box the spare strings will be removed (replaced with an empty string). If there is more strings in the "Replace" box, the spare strings will be ignored.
Insert meta tag

ReNamer Insert Meta Tag Button.png

Click the button to see a list of meta-tags.
Occurrences In case that strings occur more than once in the filename, specify which occurrences should be replaced. (Options are: first only, last only, or all)
Skip extension If this check box is selected, the extension will be ignored by the rule.
Case sensitive Will only remove a specified string from the name if the case matches exactly.
Whole words only Remove the subject text only when it is whole word, not a part of another word.

For example, searching for "bar" would not find a match in "foobar" or "bars".

Interpret symbols as wild cards Treat certain symbols as Wildcards for matching simple patterns (similar to Regular Expressions).

Wildcards

Wildcard Represents Example
*
 any number of characters (including numbers, space, underscores, etc.). abc* equals abc followed by 0 or more characters.
?
 Any single character (including numbers, space, underscores, etc.) ab?d equals abcd, ab1d, ab d, ab_d, etc.
[]
 Brackets enclose a set of characters, any one of which may match a single character at that position. foo[ab]ar equals fooaar and foobar
-
 (only within a pair of brackets) denotes a range of characters. foo[a-z]ar equals fooaar, foobar, foocar, foodar, etc.

Beware of conflicting replacements

If you enter multiple find and replace strings they will be executed as multiple Replace rules, so first string will go first and only after replacing all (or first, or last) occurrences of that string the second string in the Find box will be searched & replaced.

Find Replace
A*|*B B*|*A
Name New Name
ABBA.mp3 AAAA.mp3

You may expect the new name to be BAAB.mp3, but it's not. This happens because first all A's are replaced with B's (we get BBBB.mp3) and only then all B's are replaced with A's (and the final result is AAAA.mp3).

If you need to apply character-to-character mappings you should use Translit rule.
