Lost file, never saved

Hi, I for some stupid reason did not save a file I have been working in for two days. The app unexpectedly closed. Is it so that if i don´t save once it wont´t automatically save. I can not find the files and I am using PC.

If you didn’t turn autosave off, you should have an autosave file somewhere. In Options > Files under autosave, you can see the default location where the file is saved.
