Cannot download files from Internet Explorer(IE)? I recently tried to download a file from rapidshare from Internet explorer suddenly a message showed saying that "Internet Explorer cannot download filename from this particular web server"
though i was able to download the file using mozilla firefox and download manager such as "star downloader " and i tried to reinstall internet explorer in the control panel add and remove windows components but nothing helped and after a brief search on the google solution for it on one of the site and i came to know that the culprite was damaged index.dat file we have to delete the file and restart the computer below are the steps:-

• Open Internet Explorere
  
• Click on Tools, Click on Internet Options
• On the General tab under Temporary Internet Files, click on Delete Files
• Click Ok when it asks if you want to delete the files
• Under the History section on the General tab, click Clear History, then click Ok
• Close Internet Explorer
• Log off the current user and Log onto another user account such as Administrator
• Click on Start, Run
• Type CMD and Press Enter to open a command prompt
• Change directories to the Temporary Internet Files directory by typing the following command, substituting the correct drive letter and the word username with the correct user in Windows XP.
