Introducing FileString, a better way to share your important files. FileString is an easy to use cloud-based service that attaches a digital string to the important files you share, so you can control your content even after someone downloads it to their computer or mobile device. With FileString, you can protect files you share from being viewed, forwarded, printed or edited. You can track every time your file is viewed or printed. You can remotely update distributed copies to the latest version. And you can revoke access to files so they can never be opened again by people to whom you’ve sent them. FileString makes it simple to manage the files you’ve shared with control. It’s available on any Internet-connected computer or mobildevice and it works whether you’re online or off. FileString also automatically syncs your sent and received files – so you’ll always have access, when and where you need it. Now there is a new option to share your most important files. Don’t regret emailing an attachment and losing control of your important content. Don’t regret giving access to your shared cloud based folder permitting the download of your important file. Now you can add intelligence to your important files, and control them on all the devices you share with. Now you can “string” your most important files. Share with confidence, share with control. “String it …with File String”.
