Since QElectroTech is an open-source application for creating electrical diagrams, using a "Portable" version is a great way to keep your projects and symbols on a USB drive or a cloud folder without needing administrative rights to install it. 1. Getting the Portable Version
QElectroTech doesn't always have a single "Portable.exe" file, but it is distributed as a ready-to-run ZIP archive for Windows or an AppImage for Linux.
Windows: Go to the official download page and look for the Windows 64-bit (ZIP) version.
Linux: Download the AppImage file. This is a single file that runs without installation; just right-click it, go to Properties, and "Allow executing file as program." 2. Setup and "Portability" Mode
To ensure the app stays truly portable (saving settings and symbols in its own folder rather than your computer's AppData), follow these steps:
Extract the ZIP: Unzip the contents into a folder on your USB drive (e.g., D:\QET_Portable\).
Create a 'conf' folder: Inside the main QElectroTech folder (where qelectrotech.exe lives), create a new folder named conf.
Note: Many portable builds look for this folder to store your configuration and custom symbols locally. Run the App: Double-click qelectrotech.exe. 3. Managing Your Portable Libraries QElectroTech Portable
One of the best parts of QET is the symbol library. To keep it portable:
User Symbols: Store any custom symbols you download or create inside a subfolder in your portable directory.

If you work across multiple computers—a desktop at the office, a laptop in the field, and a PC at home—keeping your software settings consistent can be a nightmare. With the Portable version, your preferences, custom symbol libraries, and templates stay with you on the USB drive, ensuring the interface behaves exactly the way you expect it to, regardless of the hardware you are using.
Because QElectroTech runs natively on Linux ARM, you can put the portable Linux build on a microSD card. Insert it into a Raspberry Pi 5 running Raspberry Pi OS, navigate to the folder, and double-click. You now have a $50 electrical schematic workstation.
The "Portable" version of QElectroTech is a standalone executable package. It is typically distributed as a compressed archive (ZIP or 7z) that can be extracted to a folder and run immediately.
Here is why this version is a game-changer for professionals:
Once you have the portable version running, you need to tweak a few settings to keep it 100% self-contained.
