What FluentCleaner is

FluentCleaner is a free Windows utility for removing identifiable junk such as cache files, temporary data, and leftover logs. Its shared cleaning engine uses community-maintained winapp2.ini rules that specify inspectable app folders, cache paths, and registry keys. Cleanup runs only on items the user selects, and the project recommends backing up important files because deletion is permanent. Two editions use the same engine: WinUI 3 and portable Classic. WinUI 3 requires Windows 10 2004 (Build 19041) or later and the Windows App SDK 2.0.1 runtime. Classic uses .NET Framework 4.8 and is described as compatible with practically any Windows system. WinUI 3 is distributed through Windows Package Manager, while Classic is a portable download. Users can select a custom winapp2 database in Settings > Database > Custom. Silent cleanup uses the /AUTO command-line argument and can run through Windows Task Scheduler. Automatic runs append timestamps, deleted paths grouped by entry, and total cleaned size. Registry cleaning and secure file overwriting are deliberately omitted.

Who it suits

FluentCleaner suits Windows users who want inspectable rules for removing selected caches, temporary files, and logs. It also fits users who need portable or scheduled cleanup.
