Photoshop: "Not a PNG File" - File not opening

I was working on a digital drawing about 8 days ago and decided to work on it a bit more today, when I tried to open it on Photoshop it said that it was not a PNG file, despite the fact that I did save it as a PNG. (The file is even listed as a PNG in my folder.) This is the only file that isn't opening, I can't even view it in a photo-viewer. For some reason it saved itself as a PNG image, I didn't import it as such and I definitely didn't save it as such. The file was fine the last times I used it, now all of the sudden it doesn't work. There is nothing I can do to open my file. I can't view or open it with anything but I can see the preview for the image when I open Photoshop. All of my other files are able to open.

Hello. Try, in the finder folder/directory, manually changing the extension, to .jpg, .psd, tiff ...
You might have, accidentally, saved it as something else but with a .png extension and that's enough to "lock you" out of the file. (This can easily happen as one moves too quickly through things). Best, A.C.

That's exactly what I was going to recommend. It's the first thing I'd try!

... It also helps to change the "don't show extensions" default of Explorer so you can actually SEE them at the end of your file names. I have no idea who was the "genius" who decided to hide extensions as a default. That usually causes more confusion than not.

I've had PNGs fail that were definitely PNGs. Usually they'll open in Preview and I can save them from there as PNGs again. I don't know what happens to the metadata that PS can't read them. So if everything else you've done fails, you probably have a basic image program on Windows that's like Mac's Preview and if you can open and save from that. . .
