ReNamer – freeware file renamer

There are many file bulk/batch file renaming software available but this one stands apart. It is must try if you want to rename files in large number.

ReNamer is a very powerful and flexible file renaming tool, which offers all the standard renaming procedures, including prefixes, suffixes, replacements, case changes, as well as removing contents of brackets, adding number sequences, changing file extensions, etc. For advanced users, there is a PascalScript rule, which let users program their very own renaming rule.

Program allows you to combine multiple renaming actions as a rule set, applying each action in a logical sequence, which can be saved, loaded, and managed within the program. In addition, it has an ability to rename folders, process regular expressions, Unicode capable, and supports variety of meta tags, such as: ID3v1, ID3v2, EXIF, OLE, AVI, MD5, CRC32, and SHA1.

The program comes with a user-friendly interface in which you can import files and folders by using the file browser or the “drag and drop” method.

So, you can insert meta tag or text as prefix or suffix, before or after the file name, or on a particular position.

But you can also delete text from a particular position or delimiter, remove or replace it (e.g. first, last or all occurrences).

In addition, you can rearrange text by setting a new pattern (e.g. split using delimiters, positions or the exact pattern of delimiters), and set a new extension for files (optionally enable to append to the original file name and to detect by using “binary signature”).

Furthermore, you can strip the text of English characters, digits, symbols, brackets or user defined characters, change the case (e.g. capitalize every word, all lower or upper case, invert case, first letter capital), serialize text (e.g. incremental, random) or clean it up (e.g. strip out the content of brackets, replace characters with spaces).

Moreover, you can work with Translit, RegEx, PascalScript or UserInput, if you are an experienced user. Plus, you can configure filter settings (e.g. add files within folders, add folders as files, include hidden or system items), save presets, create links, disable meta tag support, add ReNamer to the Explorer context menu and set it to always be on top of other applications, and more.

This is a very well documented site in case you need help how to use the renamer.
