An alternative to the default windows 10 photo viewer.

This program exists because the standard Windows 10 photo viewer sucks so much ass. It is fucking slow and annoying.

Hold CTRL while dragging from the image window to copy the file somewhere via drag and drop.

The program now uses natural number sorting for the file list, similar to how Windows explorer sorts file names: ( a1.png, a2.png, a10.png ) instead of ( a1.png, a10,png, a2.png ).

It turned out that finding reasonable C# code that does this was tricky. Check out the NatnumSort class in this project, it doesn't allocate any heap memory, and it doesn't P/Invoke that one Windows function. As a bonus, it also preserves the (lexical) sorting order of hashes: (10a, 5ea) instead of (5ea, 10a). And it's just a static function.

The application stores user preferences such as background color and window size in %LOCALAPPDATA%. The sub folder is equal to the name of the executable without its extension, so by default it is %LOCALAPPDATA%\Windows10PhotoViewerSucksAss.

The name of the subfolder can be overridden with the bootstrap configuration; see below.

The program was hacked together in frustration and therefore the architecture is abysmal. But it's still better. Programming this was actually the very first thing I did after installing Windows 10 last year, and I've been using it since then.

The application will attempt to read an xml file with the same name as the executable file, but with ".xml" attached. E.g. if the program's executable is "Windows10PhotoViewerSucksAss.exe", then it will look for "Windows10PhotoViewerSucksAss.exe.xml".

The file is optional and looks like this:

<BootstrapData>
  <FriendlyApplicationName>Windows10PhotoViewerSucksDonkey</FriendlyApplicationName>
  <AppDataFolderName>Windows10PhotoViewerSucksDonkey</AppDataFolderName>
</BootstrapData>
