[Qgis-user] Two versions seem to be installed. I only want 3.10.13

[James H. Romer]

Hello Charles Dixon-Paver,
     Thank you very much for your very thoughtful and clear response to 
my query. I hadn't even realized that OSGeo4W64 was more than just a 
tool for downloading a version of QGIS and that it is now sitting in my 
computer for me to use. I haven't fully digested all of your suggestions 
and I'm sure I will have more questions when I have done so. But for now 
could you please explain what "starting the program with the relative 
batch file. e.g. qgis-ltr-bat" means and why you recommend it? Why 
"batch"? By now you may be starting to realize that in addition to being 
new to GIS and new to qgis, I'm not very computer-literate (whatever 
that means). Best, Jim Romer
