MassMirror is a free service that allows you to upload and share files to multiple popular file/web hosting services simultaneously. Since each file hosting service has its own share of pros and cons, you can simply paste the file download link for massmirror.com. The visitor can then choose to download the file from a file hosting service of his choice. Since the file is uploaded to multiple sites, it also ensures that a file is available for download from atleast one of the services.

Another useful thing about this service is that you can either upload a file from your computer, specify the direct download link/URL of a file from another website that you want mirrored or add a custom form to your own blog/website to upload files.

Currently the following services are supported:

4FileHosting
Badongo
Depositfiles
Megaupload
Rapidshare
Sendspace
ZShare

While uploading, a real time progress bar is displayed. After a file is successfully uploaded, a download link for the file at each file hosting website is displayed.
