Mirrorcreator is an easy to use webapp for sharing a single file across multiple file sharing services at the same time.
Mirrorcreator requires no registration and costs nothing to use. In the time it takes to upload just one file, it will spread them across multiple hosts of your choice. You can select up to 14 different file hosting sites (like MegaUpload, RapidShare, Hotfile). File sizes range from a generous 200 to 400MB depending on the host.
Post-upload, Mirrorcreator will offer an aggregated download view linking to each of your preferred hosting sites to ensure there's always a reliable option at hand. This is great for those of you have a preferred hosting service, or seeing faster downloads with a particular one.
