<p>Hi Luca,</p>
<p>There are certain files in this share/proj folder that you should not delete, because otherwise QGIS would behave strange:</p>
<p>- copyright_and_licenses.csv (not sure if it s necessary)</p>
<p>- deformation_model.schema.json</p>
<p>- other.extra</p>
<p>- proj.db</p>
<p>- proj.ini</p>
<p>- projjson.schema.json</p>
<p>- README.DATA</p>
<p>- triangulation.schema.json</p>
<p>- world</p>
<p>I also always delete all the other grid shift files that I don't need. It is getting a bit overwhelming with all these files (that you never need).</p>
<p>Greetings,</p>
<p>Andreas</p>

<p>Only if your users use transformations where certain CRSs in those areas might be involved. If you are definitely not going to use local CRSs in e. g. Germany or the US, you can remove those TIFs. If your users attempt to use those CRS, they will receive a fairly descriptive error message about certain files missing their installation so it should be easy to fix.</p>
<p>Cheers, Hannes</p>

<div>Hello,</div>
<div> </div>
<div>I am preparing the QGIS Windows package file (it's a zip file) for distribution in our organization (we don't use MSI).</div>
<div> </div>
<div>I noticed that the folder /share/proj contains TIF files and it weighs 584 MB, are they necessary for the working of the QGIS?</div>
<div> </div>
<div>Thank you and have a nice day</div>
