What it is
electron-builder downloads the tools it needs to package apps for each platform, such as NSIS, winCodeSign and 7-Zip, and keeps them here. It downloads them again the next time a build needs them.
If it's removed
The next build that needs these tools takes longer while electron-builder downloads them again.
How it's removed
