Have a large file you need to send to someone else but it's too big to email? is your answer. Senduit's service provides users with the ability to upload a file via HTTP-Protocol and receive a custom URL address to download the file from Senduit's servers. This address can be shared by the user freely and can be used to download the file a reasonable number of times. The address expires in an amount of time designated by the user (between 30 minutes and 1 week) at which point in becomes inaccessible to the public and is removed from Senduit's servers.

RapidShare was invented by Christian Schmid a few years ago when he was looking for a new option for sending and filing large files, because it was only possible to send these by email to a limited extent. He therefore developed the first 1-click file hoster, at that time under the name of ezShare, and initially as a private service. The service spread rapidly because it met a real need felt by a large number of people: to store large files quickly and easily and send the download links to friends and acquaintances. The website is among the most visited websites worldwide. An estimated 400,000 files a day are uploaded onto the company's powerful server farms.
