    <p>Hi Régis,</p>
    <p>Thanks for your explanation.</p>
    <p>The files have 0 bytes and I did not consciously create them. 
      Perhaps they should only be created on demand?</p>
    <p>Otherwise, it is good to have this auxiliary data storage option.</p>
    <p>Thanks,</p>
    <p>Andreas<br>

            <br>
            I noticed that along my .qgs (version 3) project files there
            are .qgd files with the same filename but different
            extension. They are always empty.<br>
            <br>
            Can someone help me find out what these files are and why
            they are created?<br>
            <br>
            Thanks a lot,<br>
