Hi all,
My team provides QGIS Desktop to our organization using the standalone-installer, on Windows 11. We are rolling out v3.40.6 now.
It has come to our attention that we probably need to include some extra datum transformation files for Canada.
I need to know WHERE these files / this folder should be placed for QGIS to access them.
We have a folder called "canada", and it contains .gsb and .gtx files.
Do we put this folder at this location: C:\Program Files\QGIS 3.40.6\share\proj\canada?

If not, can anyone let us know how to ensure these datum transformation files are included in our qgis installation?

Thank you,
D. Pagurek
