I now understand why some files on github do not need to be uploaded, otherwise there are many changes displayed. We just want to see the changes to the source code.
At first, I wanted to backup the entire project, so I searched and uploaded the entire project. Later I found that it might become more troublesome to check my own changes in the future, because it will show some changes to the compiled files, which may not be needed. Something, but it shows up there.
I used to think that they ignore some to save space. In fact, they are not. They do ignore it for convenience. Otherwise, it will really become troublesome to see what you have changed, because your code changes will also involve a lot of compiled file changes. The results also show that we don't actually want to watch these things, right, it makes what we look at messy.
Like the final compiled files, these can actually be ignored.
Only a small part of the changes shown below are my real source code changes, which I really want to see, the others are not and are not important.
