Rapidzearch.com is not a unique startup, but the execution is flawless.
With that said, the site let’s you search through popular file sharing sites like Rapidshare, Megaupload, MediaFire, etc. so you can find all the files you want to download.
To be blunt, you’ll be able to find all types of files (it’s up to you whether you violate copyright laws or not). The searches are pretty extensive, and all the files found through the service are active. This is great, since you won’t find anything that can’t be downloaded. If you’re looking for something that’s too recent, you might have a hard time finding it, as the site seems to take its time when indexing these popular sharing sites.
The advanced search isn’t much help, as it doesn’t offer that many advantages over the standard search. The good thing about the advanced search feature is the fact that you can search through files that have already been checked for authenticity, making it quicker for you to find the desired file.
