        \n\n\n\n
        Would you like to use QGIS on Windows without having to install the software or have administrator privileges?<\/p>\n\n\n\n
        I provide several ready-to-use QGIS Portable distributions for Windows. They allow you to run QGIS directly from a folder, USB drive, external hard drive or network location.<\/p>\n\n\n\n
        Three versions are currently available:<\/p>\n\n\n\n
        \n
        QGIS 3.44 LTR<\/strong>: the long-term release branch of QGIS 3.x.<\/li>\n\n\n\n
        QGIS 4.0<\/a><\/strong>: the first major release of the QGIS 4 generation.<\/li>\n\n\n\n
        QGIS 4.2<\/strong>: a more recent version of QGIS 4.<\/li>\n<\/ul>\n\n\n\n
        Each distribution has its own Python environment, user profile and authentication system.<\/p>\n\n\n\n

        \n\n\n\n
        <\/span>2. What is QGIS Portable?<\/span><\/h2>\n\n\n\n
        A portable application is software that runs without requiring prior installation on a computer.<\/p>\n\n\n\n
        Unlike a standard installation, all the components required by QGIS are grouped together in a single folder.<\/p>\n\n\n\n
        All you need to do is:<\/p>\n\n\n\n
        \n
        Download the archive.<\/li>\n\n\n\n
        Extract the .7z<\/code> file.<\/li>\n\n\n\n
        Open the distribution folder.<\/li>\n\n\n\n
        Run the launch_qgis_portable.bat<\/code> file.<\/li>\n<\/ol>\n\n\n\nQGIS starts without requiring any changes to your Windows installation.<\/p>\n\n\n\n The distributions can be used:<\/p>\n\n\n\n \nOn a personal computer;<\/li>\n\n\n\n On a USB drive;<\/li>\n\n\n\n On an external hard drive;<\/li>\n\n\n\n In a working directory;<\/li>\n\n\n\n In some professional environments using network drives.<\/li>\n<\/ul>\n\n\n\nImportant:<\/strong> The portable folder must be accessible for both reading and writing. Performance may be significantly reduced when QGIS is run directly from a USB drive or a slow network drive.<\/p>\n\n\n\n \n\n\n\n<\/span>3. Portable Environment Structure<\/span><\/h2>\n\n\n\nEach distribution contains the components required to run QGIS.<\/p>\n\n\n\n The general folder structure is as follows:<\/p>\n\n\n\n QGIS Portable\n\u2502\n\u251c\u2500\u2500 apps\/\n\u2502 \u251c\u2500\u2500 qgis\/\n\u2502 \u251c\u2500\u2500 Python312\/\n\u2502 \u251c\u2500\u2500 Qt6\/\n\u2502 \u251c\u2500\u2500 gdal\/\n\u2502 \u2514\u2500\u2500 ...\n\u2502\n\u251c\u2500\u2500 bin\/\n\u2502 \u251c\u2500\u2500 qgis.bat\n\u2502 \u251c\u2500\u2500 python-qgis.bat\n\u2502 \u2514\u2500\u2500 ...\n\u2502\n\u251c\u2500\u2500 QGIS_PROFILE\/\n\u2502 \u2514\u2500\u2500 profiles\/\n\u2502\n\u251c\u2500\u2500 QGIS_AUTH\/\n\u2502\n\u251c\u2500\u2500 launch_qgis_portable.bat\n\u251c\u2500\u2500 python_cmd.bat\n\u251c\u2500\u2500 osgeo4W_shell.bat\n\u2514\u2500\u2500 ...<\/code><\/pre>\n\n\n\nThe exact structure may vary slightly depending on the QGIS version and the components included in the distribution.<\/p>\n\n\n\n \n\n\n\n<\/span>Portable user profile<\/span><\/h3>\n\n\n\nThe user profile is stored in the QGIS_PROFILE<\/code> folder.<\/p>\n\n\n\n It contains, among other things:<\/p>\n\n\n\n \nQGIS settings;<\/li>\n\n\n\n User-installed plugins;<\/li>\n\n\n\n Display preferences;<\/li>\n\n\n\n Tool configurations;<\/li>\n\n\n\n Environment customisations.<\/li>\n<\/ul>\n\n\n\nEach distribution therefore has its own profile, independent of any other QGIS installations on the computer.<\/p>\n\n\n\n \n\n\n\n<\/span>Authentication system<\/span><\/h3>\n\n\n\nAuthentication data is stored in the QGIS_AUTH<\/code> folder.<\/p>\n\n\n\n This keeps the portable environment isolated and preserves the authentication settings associated with that distribution.<\/p>\n\n\n\n Important:<\/strong> Authentication information may be sensitive. The folder should be protected, and archives containing personal credentials should never be distributed.<\/p>\n\n\n\n \n\n\n\n<\/span>4. Available Launchers<\/span><\/h2>\n\n\n\nThe distributions use the official QGIS startup scripts to initialise the environment correctly before launching the software.<\/p>\n\n\n\n This approach helps prevent problems related to the initialisation of Python, Qt, GDAL and the other required libraries.<\/p>\n\n\n\n \n\n\n\n<\/span>Launch QGIS<\/span><\/h3>\n\n\n\nThe file:<\/p>\n\n\n\n launch_qgis_portable.bat<\/code><\/p>\n\n\n\n starts QGIS.<\/p>\n\n\n\n The launcher prepares the portable environment and then calls the official qgis.bat<\/code> script supplied with QGIS.<\/p>\n\n\n\n This script initialises the required environment variables and launches the application.<\/p>\n\n\n\n This is the recommended way to start QGIS.<\/p>\n\n\n\n \n\n\n\n<\/span>Open a Python console<\/span><\/h3>\n\n\n\nThe file:<\/p>\n\n\n\n python_cmd.bat<\/code><\/p>\n\n\n\n opens a Python console independently of the QGIS graphical interface.<\/p>\n\n\n\n This console uses the Python environment supplied with the distribution.<\/p>\n\n\n\n It can be used to:<\/p>\n\n\n\n \nRun Python scripts;<\/li>\n\n\n\n Use GDAL and other available libraries;<\/li>\n\n\n\n Develop geospatial processing workflows;<\/li>\n\n\n\n Prepare scripts using PyQGIS features, provided the corresponding environment has been initialised.<\/li>\n<\/ul>\n\n\n\n \n\n\n\n<\/span>Open an OSGeo Shell<\/span><\/h3>\n\n\n\nThe file:<\/p>\n\n\n\n osgeo4W_shell.bat<\/code><\/p>\n\n\n\n opens a command window configured for the QGIS environment.<\/p>\n\n\n\n It allows you to use the command-line tools supplied with the distribution, including GDAL tools.<\/p>\n\n\n\n It is also useful for running Python scripts from the command prompt.<\/p>\n\n\n\n Paths and environment variables are initialised using the portable distribution.<\/p>\n\n\n\n \n\n\n\n<\/span>5. Using Python and Developing with QGIS Portable<\/span><\/h2>\n\n\n\nThe portable environment includes a Python installation adapted to the distributed QGIS version.<\/p>\n\n\n\n You can therefore develop and run scripts without separately installing Python or QGIS on the computer.<\/p>\n\n\n\n For example, to run a script from the shell, you can use:<\/p>\n\n\n\n python my_script.py<\/code><\/pre>\n\n\n\nFor scripts using PyQGIS, the QGIS environment must be properly initialised. Simply opening Python does not always make the PyQGIS modules available.<\/p>\n\n\n\n The supplied launchers allow you to prepare this environment.<\/p>\n\n\n\n This is particularly useful in professional environments where software installations are restricted.<\/p>\n\n\n\n \n\n\n\n<\/span>6. Installing QGIS Plugins<\/span><\/h2>\n\n\n\nPlugins can be installed through the QGIS Plugin Manager, just as with a standard installation.<\/p>\n\n\n\n They are stored in the portable user profile.<\/p>\n\n\n\n The main plugins included with QGIS, particularly Processing and DB Manager, are automatically enabled in the relevant distributions.<\/p>\n\n\n\n The Lite version does not include all the advanced components available in the Full version.<\/p>\n\n\n\n \n\n\n\n<\/span>7.

Limitations of a Portable Version<\/span><\/h2>\n\n\n\nA portable distribution offers many advantages, but a few limitations should be taken into account:<\/p>\n\n\n\n \nSome Windows integrations (file associations, context menus, etc.) are not available.<\/li>\n\n\n\n QGIS updates must be performed manually by replacing the distribution.<\/li>\n\n\n\n Performance can vary significantly depending on the storage device used.<\/li>\n\n\n\n Additional plugins and libraries must be installed and configured in the portable environment.<\/li>\n\n\n\n A Lite distribution does not include all the advanced modules available in the Full version.<\/li>\n<\/ul>\n\n\n\nFor intensive everyday use, a standard QGIS installation is generally still recommended.<\/p>\n\n\n\n \n\n\n\n<\/span>9.
