Rename Multiple File

If you plan on organizing the files on your computer to declutter the system and make room for new data, you likely need a file renaming tool that's capable of significantly speeding up your job.

There are a lot of great file renaming applications out there, whether you want to add new characters to existing filenames, replace text with something else, insert numbers at the end of the base names, filter files by type, and so on.

Rename Multiple File is a pretty new product that puts emphasis on style and simplicity. Made with Electron framework, the program's wrapped in a clear-cut interface and has few but handy options dedicated to file renaming tasks.

Firstly, it's necessary to specify the path to the directory whose containing files you want to rename. Unfortunately, there's no button for browsing the computer, so you have to type or paste the full path in the window.

Secondly, you can pick the file naming option from deleting characters, setting a substring (start and end index), replacing text ("find", "with"), or inserting a prefix ("before"), suffix ("after") or both.

Thirdly, modifications will be applied to all files from the specified path after clicking "Rename now" (file filtering isn't implemented). The task's status is then indicated on the right side of the window (red highlights on errors).

Unfortunately, there's no preview or undo option available, so you have to be careful with the file renaming process. Actually, we recommend creating file backups before using Rename Multiple File. Although this isn't made clear by the application, we've noticed that it also affects file extensions and that it can delete files (e.g. when setting incorrect substrings).

All aspects considered, Rename Multiple File needs a bit more work to give users the confidence needed for performing file renaming jobs without having to worry about messing everything up.
