\\.\ tells Windows to use the device namespace instead of the file namespace. TCC asks Windows what the file system type is for \\.\c:\, and Windows says "unknown, default to FAT". And you get a FAT output.

So TCC's behavior is WAD. But I still don't know what you were trying to do or what you expected to see.
