The file is corrupt or was saved with a newer version of paint.net

Hi, as I tried to open a .pdn File I worked on before, I run into this error:

 

Application version: paint.net 4.1.6

Is there a way for me, to somehow repair this? It would be really sad if I lost many hours of work

Hello @Ask4 Welcome to the forum

 

You said it yourself in the title, the file is corrupt

 

Unfortunately, there is very little that can be done. This is why you should always make backups. If you're really desperate, upload the file and let some of the tech-heads here see if anything can be recovered.

 

You should update paint.net to the latest version, but I don't think that's going to change the problem.

 

My only other thought: is there any chance you've misnamed the file as a PDN?

Unlikely ... if the app got that far into decoding, then the file is tagged as PDN3 at the start and has a valid header and .NET serialization stream.

 

Application version: paint.net 4.1.6

 

Also, make sure you install the latest version, which is 4.2.5. That's very important!

This is the File, I thought maybe there were only a few corrupted sections, because the most of the code is still there.

It would be very nice if someone could look over it.

I put it in my Cloud, because the file is to large for me to upload it here:

Strangely, the latest version was already installed, I don't know why it copied the old version

 

I also noticed that the thumbnail in the windows explorer works fine, I don't know if this has anything to do with it

I was able to read some of the layers using Irfanview with the ImPDN plugin.

I uploaded a zip file with the extracted layers:

The thumbnail is a PNG image that is located in a different part of the file than the layer data.

Thank you so much!!!

Because of your tip with IrfanView and a little program I wrote myself, I was able to fully recreate my layers!
