Filename CheckerPowerful filename check and rename tool

Summary

Filename Checker is a powerful tool for checking and renaming filenames, in a folder and if you like its subfolders. Now you have the ultimate tool to organize your images, MP3s, etc., or to check the filenames before burning a CD/DVD.

• Checks for the length, all uppercase or all lowercase, an extension that is not lowercase, double spaces or underscores, and a number in brackets (Photo (3).jpg becomes Photo 03.jpg).
• Automatic renaming for each check except the length, or only a report of what needs to be renamed.
• Custom replace of a part of the filename, for example DSC_ by Holiday.
• The results in colors, with the reason for each file. Right-click a file to rename it by hand, delete it or open it.

Everything about using Filename Checker is in the manual. This version is a port of the original to .NET 10 for Windows 10 and 11.

Installation

If necessary, you will be prompted to install the required .NET Desktop Runtime when you launch the app. When you launch a newly released version, Windows may display a warning. If you see the message "Microsoft Defender SmartScreen prevented an unrecognized app from starting." you can click "More info" and then "Run anyway". Alternatively, open the properties of the .exe file and select the "Unblock" checkbox. Read more...
