My Photoshop autosaved after a power outage, but now I cant open my PSB

[sebastiano_5284]

I had been working on an assignment, and suddenly, my desktop shuts off. I found the autosaved PSB file in the proper place, but Photoshop is having trouble opening it. 

If i open it normally, I get:

• Could not complete your request because it is not the right kind of document.

if i open as: "

• Could not open "Mountains.psb" because it is not a valid photoshop document.

attatching the file to this post gives me the error: 

• The attachment's mountain.psb content type (application/octet-stream) does not match its file extension and has been removed.

The file is corrupt and the disk copy is probably unsalvageable.

However, Photoshop has an autorecovery - not autosave! - function which should reopen the working file in the state it was when the computer shut down.

The way this works, the RAM content is written to a hidden system recovery folder at the intervals you specify in PS Preferences. This folder is emptied and flushed in a regular application shutdown. But if the application crashes, or the power is cut, the folder is not emptied, and the content of the folder is automatically opened the next time you launch Photoshop. You don't need to do anything to find the recovered files.

So did you see anything opening when you relaunched Photoshop after the power outage?

If, however, this was a scheduled restart for e.g. a Windows update, then there would be nothing to recover.

So, i did notice Photoshop attempt to boot something up when i relaunched, but i remember the app just giving me the same response as if i opened it normally.

Opened the file i mean. Launching photoshop gave me the "Could not complete your request because it is not the right kind of document." Message

Got it. Then the recovery file was corrupted too. It can happen - if the power cuts just as the data are saved, nothing can salvage it.

Alright, thanks for confirming, i'll try to hard save more often.

I realize this doesn't help you with your current issue (no pun intended), but you should consider getting an Uninterrupted Power Supply (aka UPS or battery backup) like one of these:

I see you're illustrating step one in the boot sequence there, Bob 😄

But seriously, I have one too:
