We have lots of simple file sharing sites available online and we had recently reviewed the UploadingIt service. Lets Crate is another online service which is actually a dead simple file sharing service. The interface is so simple that you just need to drag and drop the file on to the service and it uploads the file and creates a short link for sharing within seconds. If you are using an unregistered version, the file link expires in 30 minutes.
All you need is to drag and drop the files on to the box and it will be uploaded and URL generated. If you register for their service, you can create multiple Crates (crates are basically folders and they can store multiple files).
Lets Crate also comes with a paid plan which has 10GB storage space, the free account can create a maximum of 6 Crates.
