A tiny launcher that runs OrcaSlicer in portable mode.
By default, OrcaSlicer stores its configuration in the Windows user profile (%AppData%). This launcher starts OrcaSlicer with a local data directory instead, so all settings, printer profiles and filament presets are saved in a profile folder next to the executable — your complete configuration travels with the installation, e.g. on a USB drive or in a synced folder.
- ✅ Fully portable — no installation, no registry entries
- 💾 All settings live in a local
profilefolder next to the app - 🔌 Perfect for USB drives, shared machines or multiple side-by-side configurations
- 🪶 Minimal footprint — a single small
.exe, nothing else
- Download and unzip OrcaSlicer: OrcaSlicer Releases
- Download
OrcaSlicerPortable.exefrom the Releases page of this repository - Copy
OrcaSlicerPortable.exeinto your OrcaSlicer folder (next to the originalorca-slicer.exe) - Run
OrcaSlicerPortable.exe
That's it — a profile folder is created on first start and holds all your settings from then on.
Unzip the new OrcaSlicer version, copy OrcaSlicerPortable.exe into the new folder and move your existing profile folder next to it. All your settings are preserved.
The launcher simply starts OrcaSlicer with a local data directory:
orca-slicer.exe --datadir profile
The project is a minimal C# console application (.NET Framework 4.7.2). Open OrcaSlicerPortable.sln in Visual Studio and build — no external dependencies.
