Unable to open .PDN files [SOLVED - removed .jpg extension]

[Anonymous]

I saved my old artwork i made yesterday on an older patch of paint.net. I saved the file as a .pdn and installed the latest update to paint.net. I now cannot open the file on paint.net or any other image viewing software as they do not recognize the .pdn file format.

 

Here is the error details:

 

System.ArgumentException: Parameter is not valid.

 

   at System.Drawing.Image.FromStream(Stream stream, Boolean useEmbeddedColorManagement, Boolean validateImageData)

 

   at PaintDotNet.Data.JpegFileType.OnLoad(Stream input) in d:\src\pdn\paintdotnet\src\PaintDotNet\Data\JpegFileType.cs:line 78

 

   at PaintDotNet.FileType.Load(Stream input) in d:\src\pdn\paintdotnet\src\Data\FileType.cs:line 477

Check the file name and extension carefully. I suspect you may have appended a .jpg extension.

Feel free to upload the file if my hunch is incorrect.

It looks like that Paint.NET tries to load the file as JPG and not as PDN.

If the file has the extension .jpg then rename it to .pdn and try again.

Yes, i've looked and it does have the .jpg extension, so how do i change this? I cannot upload the file as it is too large

Right-click the file in explorer to open the context menu and select Rename.

Then change .jpg to .pdn in the name.
