Needs to be migrated to newer .NET Framework version to support Long File Names.

Throws following error if path or name is too long:

ERROR: The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.
System.IO.PathTooLongException: The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.

   at Hpdi.Vss2Git.GitExporter.<>c__DisplayClass24_1.<ReplayChangeset>b__0()
   at Hpdi.Vss2Git.GitExporter.AbortRetryIgnore(ThreadStart work, MessageBoxButtons buttons)

if using runtime settings like this:

<runtime>   
        <AppContextSwitchOverrides value="Switch.System.IO.BlockLongPaths=false;Switch.System.IO.UseLegacyPathHandling=false" />   
    </runtime>

then the error become:

ERROR: Could not find a part of the path 'D:\Long\File\Path|name.sql'.

@GeyserLaPunk I'm running into this same issue. Have you attempted to upgrade it yourself?

I did, but unsuccessful, still hit the limit. The only way I was able to convert is to limit length of the output directory to the bare minimum.

@GeyserLaPunk I was able to get this working by editing a registry key on Windows 10 v1067. I also had to create an application manifest file. I used these instructions:

https://docs.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=cmd#enable-long-paths-in-windows-10-version-1607-and-later

Hope this helps! I will push changes to my fork in the next few days as well.

Maybe the program should analyze the longest file name and directory name before starting and check if they are supported. So you won't get stuck with an error after many hours.
