How does Visual Studio Code recover data after a crash? "Crash" includes both sudden power outages and handled exceptions. As examples of what I mean,
- Notepad++ has a backup folder which periodically saves copies of your files. Nothing is lost beyond the last 7 seconds even if the power goes out.
- Atom keeps an IndexedDB which should recover everything after an exception. I have no idea what happens on power outage.
- Inkscape relies on its exception handling to recover data. If the power goes out, the data is lost.
- Scite has no backup plan.

According to https://code.visualstudio.com/blogs/2016/11/30/hot-exit-in-insiders,
The way hot exit works is to periodically make backups of unsaved files. If VS Code happens to crash, a backup restore will occur the next time the folder is opened.
On Windows, the backup folder is AppData\Roaming\Code\Backups.
As for the period between backups, I haven't found anything.
