Controlling the Global User Directory

The user directory is where Dolphin stores saves, settings, screenshots, and other data. Where the user directory is located depends on the Dolphin version, operating system, and your configuration. Some locations let the user directory be shared by different installations of Dolphin (a global user directory), and some locations are tied to a specific installation of Dolphin (a local user directory).

Windows
Versions of Dolphin before always used a local user directory, stored in the same folder as Dolphin.exe and named User. In, the global user directory system was introduced on Windows. By default, the user directory is now a folder in Documents named Dolphin Emulator, but it's possible to configure Dolphin to use the old local user directory or a custom location.

Disable the Global User Directory for a Specific Build with "portable.txt"
To make a build use a local user directory, create a text file named "portable" next to the executable files of the build. With the extension it should be named "portable.txt". Dolphin will check if that file exists in the same directory, then it will not use the global user directory, instead it will create and use the local user directory in the same directory.

Custom Command Line Path
If you are launching Dolphin from the command line, you can set a custom user directory path for the current session of Dolphin by using the -u option:

C:\Path\To\Dolphin\Build\Dolphin.exe -u E:\Path\To\User\Directory\

Dolphin will use the regular user directory path again the next time you launch Dolphin, unless you use -u again.

Registry Configuration
The user directory behavior can be changed for all Dolphin installations at once using the registry. Editing the registry is an advanced topic and is not recommended for most users!

Choose the Location of the Global User Directory

 * Open the registry. Type "regedit" in the search bar of the Start Menu and hit enter.
 * Expand HKEY_CURRENT_USER.
 * Right click Software and select New &gt; Key . Name the key Dolphin Emulator.
 * Right click the new Dolphin Emulator key, and select New &gt; String Value . Name the value UserConfigPath.
 * Double click the "UserConfigPath" value and an Edit String dialog appears. Under "Value Data", enter the path to the custom User directory. Make sure that the "User" folder is explicitly specified, since Dolphin will assume whatever path it is directed to is the \User\ folder. If it is pointed to Desktop for example, the Desktop will be flooded with folders unnecessarily.

Use Local User Directories

 * Open the registry. Type "regedit" in the search bar of the Start Menu and hit enter.
 * Expand HKEY_CURRENT_USER.
 * Right click Software and select New > Key . Name the key Dolphin Emulator.
 * Right click the new Dolphin Emulator key, and select New > String Value . Name the value LocalUserConfig.
 * Double click the "LocalUserConfig" value and an Edit String dialog appears. Under "Value Data", type the number 1.

Linux
By default, Dolphin uses a global user directory and follows the XDG Base Directory Specification for determining its location. If the directory ~/.dolphin-emu exists, or you are using a version of Dolphin older than, ~/.dolphin-emu will be used as the location of the global user directory instead.

Disable the Global User Directory for a Specific Build with "portable.txt"
In Dolphin and later, it's possible to use the same portable.txt method as on Windows to set a local user directory for a Dolphin build.

To make a build use a local user directory, create a file named portable.txt in the same directory as the executable files of the build. Dolphin will check if that file exists in the same directory, then it will not use the global user directory, instead it will create and use the local user directory in the same directory.

Custom Command Line Path
If you are launching Dolphin from the command line, you can set a custom user directory path for the current session of Dolphin by using the -u option:

/path/to/dolphin/build/dolphin-emu -u /path/to/user/directory

Dolphin will use the regular user directory path again the next time you launch Dolphin, unless you use -u again.

macOS
By default, Dolphin uses a global user directory located at ~/Library/Application Support/Dolphin</tt>.

Custom Command Line Path
If you are launching Dolphin from the command line, you can set a custom user directory path for the current session of Dolphin by using the -u</tt> option:

/path/to/dolphin/build/dolphin-emu -u /path/to/user/directory

Dolphin will use the regular user directory path again the next time you launch Dolphin, unless you use -u</tt> again.
