With the advent of  website rapidshare.com, files uploading began and since then the legacy follows in slightly different ways till today.
Majority of files uploading websites now has only meant for sharing movies, songs and other files which were not the original idea when rapidshare hit the internet way back in 2002.
Earlier it held its supremacy based on ranking, number of files it hosts, percentage of file uploaders coming to a particular site, total files size. But since the movies and other medias hit the internet, their are lot more players in the game now offering lots of offers and even money.
So here is the top 10 list as of now(28th August 11) based on alexa ranking.
1) Mediafire.com – Alexa Rank -61, One of the oldest file uploading sites (but not as ald as rapidshare)  that offer unlimited downloads, unlimited uploads, unlimited storage, download resuming, zero wait times, and more, all for free.
