With increasing use of computers for various kinds of tasks, data potability is increasingly becoming an essential need. Most of us now use a desktop at home a laptop for personal work and may be another computer at workplace, school etc. Many a times it so happens that we feel the need to access a particular file which might be on another computer. The most common solution for the this is to store such files on portable drive. Portable drives have size limitations and can be easily corrupted lost or stolen so the security is a bit of a concern.
Another option is the use of remote file access software or storing files on a cloud service or a server. These services are not always free, most of them are subscription based. On the other hand files travel on 3rd party servers which are not in your control. They can be compromised and security of data cannot be said to be a 100%. Also you have to spend so much time uploading files and configuring devices.
If security and availability of data is very important for you then the solution for it is the iTwin which is a simpler solution to the problem, flash drive-like sticks that plug into either computers, and let them communicate for free over a secure internet connection.
