windows installer size is too large when use template electron-builder.yml files setting

[SD-Gaming]

Originally, my intention was to create a Windows installer.

Step

Initially, I execute npm run build:win, and the resulting dist\setup.exe installer exceeds 1GB in size. The largest file is dist\win-unpacked\resources\app.asar, which is approximately 1GB.
Deleting the \out directory and rerunning the script reduces the installer size to approximately 300MB. After commenting out the electron-builder.yml - files code, the final installation size decreases to 100MB.

Question :

1. Should I sometimes delete the \out directory after making a mistake?
2. why use the template files setting cause the installer is much bigger than use electron-builder default setting?

Usually, it’s about 70m under Windows. You may mistakenly package the dist directory repeatedly. electron-builder files is required. You can verify it through npm create @quick-start/electron@latest. There is no problem with the default electron-builder configuration.

Thank you reply.
I have compared the @quick-start/electron, but can't find which reason causes that repeatedly package the dist directory.

After all, I rm node_modules directory re-install the package, and uncomment the electron-builder.yml files code. the installer size is normal.
Leave this topic alone and maybe help someone else.
