need help finding a hidden folder

1) Download the application called RAR at

http://www.rarlabs.com/rar/rarosx-3.5.b5.tar.gz

2) decompress that file and there'll be a folder called "rar" (no quotes)

3) in that folder there's a file called "rar" (with no quotes)

**** IMPORTANT NOTE!!! -> If you don't know what you are doing in this next step you can totally destroy your whole computer, so proceed at your own risk. ****

4) do a search on your hard disk for an invisible folder called bin. This will be in the parent folder usr.

5) drag the FILE called "rar" in to that bin folder. It will ask you for your password, so go type it in and continue.

6) open the terminal and go to the directory that has the file or files you want to rar. (for more info on how to do basic things like change directories in the command line, do a search for that info)

7A) once in the folder housing the files you want to rar, type this

rar a WhateverRarFileNameYouWantHere

7B) to make a multi file rar archive, type the following instead of the above and replace where you see "####" with the file size you want each part to be, in kilobytes (kb).

rar a -v#### WhateverRarFileNameYouWantHere



8) to create par files for that rar archive you just created, just use MacPar Deluxe and save your self any further trouble
