Broken File After Power Failure

Can someone tell me what is happen ?
I’m just working normally, but i have power failure. Reopened the project just end like image top, i’m loss my 2 days working.

It is always advisable to have a backup and recovery plan for such events (not just in Atom, but in general).
Here is one package to try.

project-history

Back to your lost file … anything in cache?

I did install the package, nothing happens.
I forgot to backup the file, my bad. How to find the cache on Windows ?

The suggestion was made to offer some insurance against future loss. Nothing you can do about past loss.

Read the project-history manual …

Maintaining local history of files (history of your changes to the code files).
