Unfortunately, no, it cannot be recovered.
Simply, you need to go to this directory
C:\Users\***\AppData\Roaming\Adobe\Adobe Photoshop CC 2015\AutoRecover
where the Auto Recover folder in present.
The App Data folder by default is hidden and therefore you need to change the folder settings for this purpose. You will find the last used file in the Auto recover folder in .psb format, which you can open up to get back to that particular unsaved file.
oh my god ik this is late but you are a lifesaver thank you sooo much
can this be done in a mac also?
or just pc?
On a Mac: User > Library > Application Support > Adobe > Adobe Photoshop 20XX > AutoRecover
if there is no files , i apologize from you , you can't recover them ,
Is it possible to recover a photo that you editted through the open button? For example, if you were to open a photo in photoshop, draw something on it, and accidentally clicked do not save when you closed it, would it appear in the Auto Recover file?
Unfortunately, no. "Do not Save" means exactly that. What you did is properly exited the program.
Autorecover is for when Photoshop crashes, and did not give you a chance to save or not.
You may want to save a copy every 5/10/15 minutes to a backup folder or if on a Mac, use Time Machine.
