The main advantage that file-sharing services provide is that they establish a platform for non-tech people to have a location to transfer files to and then assign access privileges to those files for others to view and/or modify.
And unlike online storage services of the 90s, it doesn’t matter whether you’re connecting with a Mac, PC, Android phone, or iPad; you will enjoy the same look and feel no matter what platform you’re using.
That makes it a lot easier to share files with clients and vendors where you simply don’t know if they have multiple devices on the same platforms as yours.
Such onsite and cloud storage solutions also allow you to access files from anywhere in the world. You can sit at the airport working on your laptop for a presentation. Then you connect with your tablet on the flight to continue your work without having to copy files to different locations and manage different versions.
