CheckItOut
CheckItOut is a digital file checkout system that allows you not only to share files, but to make sure only one person uses a file at any given time. This solution is ideally suited to engineering or programming firms that need a way for remote users to access files, but also need to make sure that these users don't overwrite each others' work. With CheckItOut, when a file is checked out, it's locked until that user checks it back in. Click here for the live demo!
