Dropbox is one of the most popular online file storage/ sharing services currently available. Here is what makes Dropbox so popular.

Cost – Dropbox is completely free, with no hidden charges leaping out at users at any time.

Capacity – Users are given 2 GB of storage capacity. This may not seem like much, but it is certainly plenty to start off with. Adding storage is also possible – and without incurring charges. Users have a whole array of free options to increase their storage capacity, including, among others:

Invite friends/ acquaintances to Dropbox
Connect Dropbox to Facebook/ Twitter
Send Fan mails

Convenience – Extremely easy to use, Dropbox can either be used online or by installing the Dropbox application. This is quick, easy to do and allows automatic saving/ synchronisation of files between devices (which should also have the application installed) without having to use a browser.

Accessibility – With the app installed, it is possible to access files from wherever a user is, any time on any device, even if offline at the time (the Dropbox folders on all devices are updated automatically every time a file is saved). Mobile users are able to download only required files in order to save space.

Sharing – Files can be shared with individual users or public by designating folders to specific users or enabling them for public sharing.

Back-up – Dropbox is a convenient solution to backing up files in a safe and easy to access fashion. By storing files in the cloud, data sticks, CDs, DVDs and other easily lost or damaged storage devices – and the cost involved – become a thing of the past.

What’s more, deleting files accidentally will not result in losing them, because Dropbox keeps easy to retrieve copies of all deleted files for 30 days.
