Once you have uploaded a file to one of these services, file-sharing is as easy as clicking a “share” button and then sending the link to a colleague via email. Giants like Dropbox, Box, Google, Microsoft, and Apple, as well as smaller companies like MediaFire and Tresorit, all offer online cloud storage options that include file sharing, synchronization across multiple devices, and collaboration features. Today’s world of file sharing offers nearly endless options. Emails could also be sent (and many people still use email as their main “file-sharing” option), but size limits on attachments and security concerns discouraged this practice. Back in the pre-cloud days, sharing files involved using file transfer protocol applications or else copying files to a disc and then mailing it or walking it over to a colleague (affectionately known as ‘sneakernet’).
