Broken Paint.Net Files

[SebG]

I tried opening some files of mine, but instead I receive the: 
"there was an error while opening the file"
Here's the rest of the information: 

Exception:

System.FormatException: file is not a valid paint.net document
   at PaintDotNet.Document.FromStream(Stream stream) in D:\src\pdn\src_4_3_x\Data\Document.cs:line 1354
   at PaintDotNet.Data.PdnFileType.OnLoad(Stream input) in D:\src\pdn\src_4_3_x\PaintDotNet\Data\PdnFileType.cs:line 31
   at PaintDotNet.FileType.Load(Stream input) in D:\src\pdn\src_4_3_x\Data\FileType.cs:line 498
   at PaintDotNet.Functional.Func.Eval[T1,TRet](Func`2 f, T1 arg1) in D:\src\pdn\src_4_3_x\Base\Functional\Func.cs:line 158
 

Anything I can do about this?

Maybe you saved the file with the wrong extension.

You could check the file type here https://www.checkfiletype.com/

 

It determines the file type based on the file's contents (not the extension) and it understands Paint.Net files

Seems you have it in "D" drive - perhaps that's why?

This line is for developers (it's called stack trace by programmers). It basically shows the path and line of the source code where the error is happening. So the developers can examine the code and act if required. In this case, it's on Rick's computer, not user's.

 

Only the first line has importance for end-users: file is not a valid paint.net document.

Many thanks for explaining that tidbit @otuncelli 😁 As you can see, I'm not that familiar with code.

 

There is a Plugin @SebG called "What's It" that proffers this:   Sorry, there seems to be an issue with this Plugin and the latest version of Paint.net (now working again).

 

"If Paint.NET fails to open an image then you may check with this tool if the
file extension is wrong and correct it."

@SebG
You can use a freeware called 'Metadata++' to examine the questionable image for its EXIF data and the app will reveal its file type.

Here is a link to the web site where the app can be downloaded:
Logipole - Official Homepage of Metadata++, Konvertor, Flash 32 and Albm++

 

(BTW- If you are not keen on dark mode, goto the settings in Metadata++ and uncheck it)
