Do you mean instead "you have a file with a TAR extension and you don't have the program to extract files from it"?

I need an upgrade driver or program for .tar files.
Don't have a clue what your talking about here. This could mean you want a upgraded driver in TAR format or you could need a program to extract TAR files. Please clarify your request. There are files with other formats that work just as well like EXE or ZIP.

If you are wanting a driver.... what is the hardware your needing it for?
