The .bat file is a DOS batch file which will join the parts without
having to use a file joining program. You can open it up in a text
editor like Notepad to see what it actually does. Running an unknown
batch file can be extremely dangerous however, so it's usually best to
leave them alone.
The .crc file is used to verify the integrity of the data, and can be
very useful. It stands for Cyclic Redundancy Check. Basically, it's
a way to make sure that the file you downloaded is exactly the same as
the original file. Sometimes files get corrupted in transmission, and
it's not always obvious just by looking at the sizes. A quick crc
check will tell you if there is a problem or not. If you use JAS to
join the files, it will automatically check the crc values for you. Or
you can use other software, such as QuickSFV to do this. With the
advent of par and par2 files, crc checking is perhaps not as valuable
as it once was. But it's always nice to have the option available,
and still very useful on it's own.
