5 years ago Hello, sorry that the data were lost. Unfortunately, data loss are highly possible if you do not give a chance to your computer to shut down properly. Data loss per se is not GanttProject fault, it is the way operating system works. OS may cache files in memory (and it does) and in case of power outage cache never hits the disk, or hits the disk partially.
You may try recovering files using special tools. Here is the first which I stumbled upon. Never tried it, though: https://www.ccleaner.com/recuva
Another issue is that GanttProject itself could provide recovery. We really do: we make a copy of project file on every undoable action. However, they well may stick in the write cache too or may be deleted from their temporary folders. Besides, GanttProject removes stale copies when it starts, so we recommend running Help > Recover immediately after detecting file corruption.
You said you were unable to recover with Help > Recover. Can you provide more details? Did it suggest any files but failed to read, or there were just no files to recover from?
I hope it helps at least with understanding the underhood of the issue. I really doubt that we can do anything with fighting power outages, it is beyond the application responsibilities. Recovery might work better, but as I said, it is also not a guarantee in case of power outages.

I shut off my computer yesterday without properly closing my project file and the project file will not open now. The error message says "content is not allowed in prolog.". If I edit the file with Notepad++ it is filled with NUL. I'm unable to recover the file through "Help" -> "Recover". I'm assuming it is gone forever but wanted to post the issue.
Here is the log. Thank you.
