FluentCleaner Classic Portable - Where Are Custom Settings Stored?

[ljmacri]

I am currently testing FluentCleaner Classic Portable v1.10.099 (FluentCleaner-Classic-net48.zip) that I unzipped on a removable USB stick.

For my first test I disabled all cleaning options except Windows Temporary Files and clicked "Analyze" (see image below), but I did not click "Run Cleaner" to remove the 349.6 MB of temporary files it identified for removal.

I confirmed that my custom settings were retained after I closed and re-opened FluentCleaner Classic Portable, but I can't find the INI configuration file (e.g., fluentcleaner.ini) where those settings are stored. Does that mean that FluentCleaner Classic Portable stores the program settings somewhere in the Windows registry, and if so what is the location of those registry entries?

As a long-time user of Piriform's CCleaner Free Portable v6.x I am accustomed to seeing my custom settings saved in a file called ccleaner.ini that I can copy and paste to transfer my custom settings if I unzip the portable build (e.g., ccsetup641.zip) in a different location.

FluentCleaner Classic does not store its settings in the registry
By default, they are saved here:
%APPDATA%\FluentCleaner\settings.json
for a fully portable setup, place settings.json next to FluentCleaner.exe on the USB drive and restart the app. that local file then takes priority, and all settings travel with the application

starting with version 1.11, settings can also be exported and imported directly from Options > About, no manual AppData digging required

Hi Belim:

Problem rseolved. I tested your suggestion to copy my "old" JSON file at %APPDATA%\FluentCleaner\settings.json I was using with FluentCleaner Classic Portable v1.10.099 over to my removable USB stick when I updated to v1.11.112 (re 06-Aug-2026) today and I was able to retain my previous configuration settings.

Thanks as well for the link to mikolajek's 16-Jul-2026 How to preserve settings when updating?. I must have entered the wrong key words when searched this discussion board for a topic on the same subject.
