I received some .PDN Files and when I tried to open them in Paint.Net I got this message There was an error opening this file and when I went to see the details it said this
Application version: paint.net 4.1.6
System.FormatException: bad TGA header
at PaintDotNet.Data.TgaFileType.OnLoad(Stream input) in D:\src\pdn\src\PaintDotNet\Data\TgaFileType.cs:line 376
at PaintDotNet.FileType.Load(Stream input) in D:\src\pdn\src\Data\FileType.cs:line 496
at PaintDotNet.Functional.Func.Eval[T1,TRet](Func`2 f, T1 arg1) in D:\src\pdn\src\Base\Functional\Func.cs:line 158
How can I fix this file so I can open it?
