Has anyone used a good "virtual" share drive solution they would recommend. In many cases, these are advertised as virtual backups (such as IDrive). We need to be able to securely store up to 2GB of data and up to 5 users will be uploading, downloading and editing the documents. One critical requirement is if a user attempts to open a document and another user is already editing it, the first user needs to be notified and could only open it in read-only. Also, we want to be able to drag and drop as well as copy and paste to and from MS Outlook. Finally, the amount of time it takes to download a document needs to be relatively fast (similar to what it would take to download the document from any other website). We've tried a couple of solutions and each has failed on one or more of these criteria so hoping someone can help. Feel free to PM me if you'd prefer. Thanks
