ZetaLongPaths can't move files from long source path on Windows Server 2012

There is an exception when ZetaLongPaths moves files from long source path on Windows Server 2012. Operating system is up to date. Source path + name of file limit is 256 chars, after this length the problem starts to occur.

Method:

ZlpIOHelper.MoveFile(source, destination);

Exception:

System.ComponentModel.Win32Exception (0x80004005): Error 123 moving file '\\?\C:\Program Files (x86)\xxxx.txt' to '\\?\D:\xxxxx.txt': The filename, directory name, or volume label syntax is incorrect. at ZetaLongPaths.ZlpIOHelper.MoveFile(String sourceFilePath, String destinationFilePath, Boolean overwriteExisting) in c:\P\ZetaLongPaths\Source\RuntimeNetCore\ZlpIOHelper.cs:line 489

Is there any solution to this problem?

Yes, fine, until there is a workaround I’m happy 😃

There is some inconsistence:

1. When moving file to destination path that is short and contains \\ - this works.
2. When moving file to destination path that is long and contains \\ - this do not work.

I think this should work the same whether path is long or short. If \\ is legal in path it should work in short and long path. If \\ is illegal in paths it should not work in both short and long paths.

I can’t tell how to fix this in code. I managed to fix our internal code to not to generate \\ in paths.
