All you need is firefox with the imacros addon. copy and paste this script into a new macro and it will do all the work for you. here are the steps fallowed by some screenshots 100% TESTED AND WORKING!

1. find the rapidshare links you want to download

2. copy and paste the first link into the script. (URL GOTO=http://www.rapidshare.com/blah blah blah blah)

3. depending on your download speed set the wait time at the bottom.

4. copy and paste the script again changing the goto url to part 2 then 3 and so on. (you can add as many links as you want.)

5. save the changes and run the script from i macros. ( it will automatically click the buttons, wait for timers, and download the file to your imacros download folder). (c:/user name/mydocuments/imacros/downloads) then it will start the next part.

EDIT: rapidshare is now giving longer wait times and sometimes has a 15 minute wait time between downloads so i lengthened the first and second wait timers. adjust them to suit your speed by setting them just a bit longer than your extremes (ie: 25min DL so i say 35min dl in case of slowdowns and the 15min wait so i set the bottom timer for 50min)

link to download imacros for firefox
Code:

imacros download script
Code:

TAB T=1
URL GOTO=http://www.rapidshare.com/files/104114823/Idl_Hnds.part1.rar
TAG POS=1 TYPE=INPUT:SUBMIT FORM=ID:ff ATTR=VALUE:Freeuser
WAIT SECONDS=170
ONDOWNLOAD FOLDER=* FILE=* WAIT=YES
TAG POS=1 TYPE=INPUT:IMAGE FORM=NAME:dlf ATTR=SRC:http://*.jpg
WAIT SECONDS=3000

NOTE: the wait time at the end of the macro is very important. it must wait longer then the download takes or else the download will cancel. set it 5-10 minutes longer. if you close the macro before the download finishes the download will cancel. also sometimes it adds numbers to the end of the files you download, delete these numbers in all parts to extract the files from the archive. (ie: Application.part1_20080929_145100.rar should be Application.part1.rar)
