ReNamer

If you've ever found yourself staring at a folder full of disorganized files with messy names, you know how tedious renaming them one by one can be. That's where ReNamer comes in a small but incredibly powerful tool designed to handle batch file renaming with ease and flexibility.

At its core, ReNamer offers all the essential renaming features you'd expect. You can add prefixes or suffixes, replace specific text, change letter cases, or even strip out content inside brackets. It also lets you insert number sequences for better organization and modify file extensions in bulk. But what really sets it apart is its depth. Beyond the basics, it supports programmable renaming rules through PascalScript, meaning if you can imagine a renaming pattern, you can probably code it.

One of the handiest things about ReNamer is how it lets you combine multiple actions into a single rule set. You can stack operations like first removing brackets, then adding a counter, and finally changing the case and preview the results before committing. This rule set can be saved and reused later, which is a huge time saver for repetitive tasks.

Power users will appreciate its support for regular expressions and metadata tags. Whether you're working with MP3s (ID3 tags), images (EXIF), or even checksums like MD5 or SHA1, ReNamer can read and use that data in renaming rules. And yes, it works on folders too, not just files.

Despite its advanced capabilities, ReNamer remains lightweight and user friendly. The interface is straightforward, and there's a helpful getting started guide if you're new to batch renaming. It’s the kind of tool that doesn’t get in your way but delivers serious power when you need it. If you deal with large numbers of files whether for work, media organization, or just keeping your digital life in order ReNamer is definitely worth trying.
