Life After mesh model file

[Durik256]

i know that they are .mesh files

but there may be textures and other files. I made a console application that changes the extension depending on the first 4 bytes of 'magic'. maybe [.mesh, *.dds, *.gis], other files will remain unchanged.
just drop a file or directory on it and it will scan all the files in the folder.
tested on "_Unknow" folder.

                bool flag = File.GetAttributes(args[0]).HasFlag(FileAttributes.Directory);
                string[] files = Directory.GetFiles(flag ? args[0] : Path.GetDirectoryName(args[0]));
