If you are interested, i have a fork of this tool , with some modification (noUAC and PortableMode).

PortableMode behaves like you want, it checks for the presence of the file portable.txt, and if found it starts in portable mode.

Obviously, it's your choice if you want to stay with the Original or the Fork i modded.

if you are interested, you just need to replace

• in "Ps3DiscDumper\Settings.cs" (Defaults Dumps/IRD Folder)

public string OutputDir { get; set; } = (File.Exists(Path.Combine(Directory.GetCurrentDirectory(), "portable.txt"))) ? Path.Combine(".", "dumps") : ".";
public string IrdDir { get; set; } =  (File.Exists(Path.Combine(Directory.GetCurrentDirectory(), "portable.txt"))) ? Path.Combine(".", "ird") : Path.Combine(Environment.GetFolderPath(SpecialFolder.ApplicationData), "ps3-iso-dumper", "ird");

• in "Ps3DiscDumper\SettingsProvider.cs" (Default settings.json Location)

settingsFolder = (File.Exists(Path.Combine(Directory.GetCurrentDirectory(), "portable.txt"))) ? Directory.GetCurrentDirectory() : Path.Combine(Environment.GetFolderPath(SpecialFolder.LocalApplicationData), "ps3-disc-dumper");

i have tested this under Windows and Works, on Linux or Mac i dont know as i dont own a Mac, and dont use Linux.

Hi @x7l7j8cc , thanks for letting me know. Maybe you could just raise a PR?

@kathyrollo I can't, because doing a PR will do a complete Pull of my Fork, even unwanted ones...
So i think it's best if @13xforever does the 2 changes manually, they are very simple and easy to do, i even listed the files interested for a quick change.

It's up to @13xforever if he wants to do the changes or not.

@x7l7j8cc Will probably just wait for the official changes then. Thanks anyway.
