Francheezy: First you must make sure you have
the full set of the rar files. It will
start from filename.part01.rar and
end with filename.part21.rar (if the
total is 21 files).
Then right click on the
filename.part01.rar and select
"extract here". Notice the extracted
file is much large than all 21 rar file
combined. That means you had
successfully extract it.
