Overview of Rules

ReNamer has an extensive set of rules. These rules can be combined together, in a logical sequence, to perform nearly any thinkable operation with the filename. You can also manually edit the name of any file.

The table below lists all rules, with a brief description of each rule.
The subsequent chapters provide more details for each rule (follow the links).

Rules Description
Insert Insert the specified text into the filename: as prefix, as suffix, at the specified position, before- or after the specified text. There is also an option to insert meta tags into the filename.
Delete Delete a portion of the filename, usually defined by character positions: from the specified position, from the occurrence of the specified delimiter, until the specified number of characters, until occurrence of the specified delimiter or till the end. This rule can be set to process the filename in a right-to-left manner.
Remove Remove the specified text from the filename: first, last or all occurrences. Optionally, wildcards can be used within this rule, to remove masked text fragments.
Replace This rule is very much like the Remove rule (above). It has similar options, except that instead of removing the text fragments, it will replace them with the specified text.
Rearrange This rule allows you to chop up the existing file name by any delimiter or position and reuse any/all of the parts in any order to compose a new name.
Extension Change extension of files to the specified extension, or to the extension automatically detected through the internal database of binary signatures.
Strip Strip all occurrences of the specified characters from the filename. This rule has predefined character sets, like digits, symbols, brackets, but you can also define your own character set.
Case Change the case of the filename: capitalize each word, to lower case, to upper case, invert case, or capitalize only the first letter and force the rest to lowercase (as in a sentence). There is also an option to force case for the manually entered fragments, for example: CD, DVD, India, ReNamer, etc.
Serialize Use numeric incremental or random sequences of digits to put filenames into an order.
CleanUp Cleanup filenames for (or from) commonly used naming conventions for Internet, peer-to-peer networks, and other resources.
Translit Transliterate Non-English characters from different languages into their English/Latin representation. Useful for preparing files for network storage and transfer. Several transliteration maps are built in, and you can define your own maps.

RegEx (=Regular Expressions) is used for complex pattern/expression matching and replacing operations.
Although it may look complex at first, you can learn it quite easily, using the guide provided in this manual!

PascalScript Scripting allows programming-aware users to code their own renaming rule using predefined set of functions. This rule uses Pascal/Delphi programming syntax and conventions. Extremely powerful feature in the right hands.
UserInput Rule that simply sets the new names of the files to the names entered in a list (one name per line).

Each of these rules are explained in the following sections.
