How To Use Dropbox on Your iPhone

With cloud storage becoming more popular, cost effective, and accessible, many different tools and services seem to be cropping up in the market almost every week. Dropbox remains one of the most popular services available (and we’re big fans of it at Mac.AppStorm!).

If you are not familiar with Dropbox, it’s probably worth reading our article “Delving Deeper Into Dropbox” before you continue.

A few weeks ago, Dropbox revealed their iPhone application to make your file syncing life even easier. It’s completely free, and available from App Store. Today I’ll be walking you through the setup process, and explaining what the mobile Dropbox app is capable of.

Getting Started

To run Dropbox for iPhone you need an iPhone (any model) or iPod Touch with iPhone OS v3.0 or later installed. Installing and running Dropbox app is just like other iPhone apps. Once you run it, you will see a welcome message with two options to select:

  • I’m already a Dropbox user
  • I’m new to Dropbox
Setting up Dropbox

Setting up Dropbox

I assume that you are already a Dropbox user, enjoying your online sync-space, so click "I’m already a Dropbox user" and enter your Dropbox account in the next screen. If you don’t have an account, you can quickly make one by tapping "I’m new to Dropbox" and take it from there.

After a successful login, a welcome note will open to give you a glimpse of what you can do with the Dropbox app. It is actually a PDF file and you can read it later on.

The Welcome Document

Tap on "My Dropbox" on top of the screen or alternatively on the menu bar (bottom) to see a list of your files and folders in the root folder of your Dropbox account. You can scroll down the list and open various folders and files. It is quite easy to find your files as they are sorted by name (similar to iPhone contacts) as well as each item showing the file type, size, and the last modification date.

Viewing Your Dropbox

Viewing Your Dropbox

Tap on any item to check if Dropbox is able to open (or preview) the contents for you. Various files are supported and can be opened on iPhone/iPod Touch (check the corresponding help page for more details):

  • Images (.jpg, .tiff, .gif)
  • Music (.mp3, .aiff, .m4a, .wav)
  • Movies (.mov, .mp4, .m4v)
  • Apple iWork files (Pages, Numbers, Keynote)
  • Microsoft Office files (Word, Excel, Powerpoint)
  • Adobe PDF (.pdf)
  • Web pages (.htm, .html)
  • Text and rich-text files (.txt, .rtf)
  • Contact vCards (.vcf)

In the next screenshots, you can see a Numbers spreadsheet being previewed successfully. You may zoom, or go through the pages, but as you expect you can’t edit anything, simply because this is not an office application.

Doing More With Dropbox

Opening and viewing the contents of documents is not the only thing you can do with Dropbox on your iPhone.

To share a file with others, simply open it in the preview mode, then click the envelope button on the the menu bar (lower-left) to send it as an email attachment. Easy. It goes without saying that you should enter the recipients and tap "Send" to actually send the file.

To upload photos or video clips to your Dropbox space, you need to first create a shared folder, which can be easily created through the web interface. To get more info on this, check the official help.

Once you have created a shared folder, open it in the iPhone app. Then tap the camera button (top-right) to take picture or video. It will be automatically uploaded to the shared folder, so everyone with access to that specific folder can see your pictures or video clips.

Only iPhone 3G S can take video clips. Other iPhones take photos only.

There are times that you will need to remove a file from your Dropbox repository (folder). Swipe your finger left-to-right over any file in the files list (see figure 5), and a "Delete" button will appear. Tap the "Delete" button to remove the file from your Dropbox account.

Accessing Files in Offline Mode

To access some files in the offline mode, when you don’t have access to Internet, you need to mark them as a ‘Favorite’.

Simply tap on the "star" button in the menu bar when a file is opened and Dropbox will store a local copy of the file in your iPhone. Note that the local space is limited to 2GB and the app won’t allow you to download a file when you have insufficient free space on your device. This is a limit made by Apple for any iPhone app, so don’t blame Dropbox!

Once a file is marked as "favorite" it will be listed in the Favorites tab for quick access:

You can remove a file from Favorites tab anytime by swiping you finger left-to-right on an item and tapping "Remove". The file will be removed from the Favorites list as well as the iPhone flash drive (local storage), but it will still remain intact in your Dropbox account.


There is not much to say about settings because fortunately there isn’t anything to configure. But you can still open the Settings tab and update your login information, check the available space in your Dropbox account, or unlink the app from your account (for security reasons).

The Dropbox iPhone app takes both cloud storage and the iPhone storage to the next level. Not only do you have access to your online file storage in your pocket all the time, but also you are extending the storage capabilities of your iPhone.

It’s a really impressive application, and well worth downloading if you’re an existing Dropbox user!
