Recovering files i forgot to save in Photoshop

Hi there,

It won't be possible to restore the document that was not saved. Did Photoshop gave you a warning stating work in progress or unsaved data will be lost? 

Also, which exact version of Photoshop are you using and on which OS?

There are a certain scenarios where a damaged file can be recovered. See https://helpx.adobe.com/photoshop/kb/file-recovery-photoshop.html

Thanks,
