Is it possible to make QGIS 3 portable with changed location for Qgis setup parameters folder.
For QGIS 2 it looked like this in qgis.bat file:
qgis --optionspath "X:\qgis" --configpath "X:\qgisini"
For QGIS 3 it doesn't work. Setup parameters are default placed in:
C:\Users\xxx\AppData\Roaming\QGIS
Those parameters have been removed in favour of the new --profiles-path option. You can set this to the root folder that will contain the profiles for the sessions
--profiles-path C:\temp\myqgisprofiles\
On Windows make a shortcut to the qgis-bin.exe and attach the parameter to the 'target' field.
This will make
C:\temp\myqgisprofiles\profiles\default
When run the first time.
Profiles are a new feature in QGIS 3 to keep settings and plugins, etc isolated from each other.
...AppData\Roaming with warnings: Unable to load C:\qgis-bin.exe Unable to load C:\QGIS3.0\bin\--profile-path. A part of my qgis.bat start "QGIS" /B "%OSGEO4W_ROOT%"\bin\qgis-bin.exe --profile-path "%OSGEO4W_ROOT%"\myqgisprofiles %*
The given option in the above answer is incorrect (profile instead of profiles) - the correct option is:
--profiles-path C:\temp\myqgisprofiles\
You can see the complete list of command line options of QGIS by running it in the command shell using the command line option --help:
qgis-bin.exe --help
(Running QGIS 3.0.2)
BTW: I don't have enough reputation yet, to add this as a comment to the answer above ...
...AppData\Roaming\OGIS3,not in `C:\temp\myqgisprofiles` link to my qgis.bat
In the same place of the file OSGeo4W.bat, create a bat file with the instructions:
@echo off
call OSGeo4W.bat make-bat-for-py
call OSGeo4W.bat o4w_env
call OSGeo4W.bat py3_env
call OSGeo4W.bat qt5_env
call OSGeo4W.bat qgis --profiles-path %OSGEO4W_ROOT%\Profiles\
To this point, I have not been able to execute grass scripts, but work fine SAGA and GDAL
If want use Grass script edit the file grass74.bat
in the text:
SET OSGEO4W_ROOT=@osgeo4w@
with the text:
SET OSGEO4W_ROOT=%OSGEO4W_ROOT%
It seems "--profiles-path" option is enabled in case of using with "--profiles-name" .
example in bat file
start "QGIS" /B "%OSGEO4W_ROOT%"\bin\qgis-bin.exe
--profiles-path "%OSGEO4W_ROOT%\settings" --profiles-name default
...AppData\Roaming
This batch seems to work, adding a /qgisconfig directory in the current one to store QGIS config :
set DRV_LTR=%~dp0
REM set a specific Qgis variable with a variable setting before
set OSGEO4W_ROOT=%DRV_LTR%qgis
REM add a new path to the system path
path %PATH%;%OSGEO4W_ROOT%\apps\qgis-ltr\bin;%OSGEO4W_ROOT%\apps;%OSGEO4W_ROOT%\bin
REM if the bat file find one argument (project name), open it. Else open a Qgis program with a new empty project
if "%1" == "" (start "QGIS" /B %OSGEO4W_ROOT%\bin\qgis.bat --profiles-path %DRV_LTR%qgisconfig) else (start "QGIS" /B %OSGEO4W_ROOT%\bin\qgis-ltr.bat --profiles-path %DRV_LTR%qgisconfig --project %1)
