How to use dropbox

This entry is part 8 of 15 in the series Cloud Computing


Dropbox is one of the web’s most popular cloud services, and has now been around for more than a decade. Since its launch, it’s matured and expanded enormously – but the chances are you’re not using half of its features. There’s no shame in that – the software does such a good job of fuss-free file synchronization that you’ve probably never felt the need to pore over the documentation and discover what else it can do.

It’s time to put that right. Over the next few pages, we’ll introduce some of the most useful tips and tricks that will transform you from a Dropbox novice to a box-smart storage master.

How does dropbox work?

Dropbox is designed with multiple layers of protection, distributed across a scalable, secure infrastructure. These layers include:

  • Secure data transfer
  • Encryption
  • Network configuration
  • Application-level controls
  • User-level controls

Who owns dropbox

At the $10 billion valuation, Houston’s stake in the company he cofounded with Arash Ferdowsi, could be worth anywhere from $1 billion to $1.5 billion, depending on how much he still owns. A spokesperson for Dropbox did not respond to an email request for comment.

How to download from dropbox?

Top right hand corner next to open tab there is a tab with three dots. This is “more” click on it and the drop down menu will have download in it. Download the docs you want to you computer.

By default, Dropbox syncs all your files across every computer on which it’s installed. That’s not a problem on a fast PC with a capacious hard disk, but it could bog down a lightweight laptop. To have only certain files and folders sync to a particular computer, open the Dropbox client on that system and navigate through its preferences to the Sync tab. Here, click “Choose folders to sync”, and untick the ones you don’t want synchronised to that machine.

Bear in mind that if you disable syncing of a particular folder across all of your computers, the only copy will be the one on Dropbox’s cloud servers. Dropbox makes reasonable efforts to protect your data, but you should never trust your originals to a third party. Make sure you have at least one other copy of every file offline, even if it has to be archived to an external drive or optical disc.

While we’re in Preferences, switch to the Bandwidth tab and make sure the LAN sync option is enabled. This will use your local network to synchronize files between neighboring PCs and Macs that are logged into the same Dropbox account, which means quicker syncing and less tying-up of your internet connection.

If you want to free up more internet bandwidth, adjust the download and upload rates, which

by default are set to no limit and an automatic limit respectively. Specifying a lower cap may allow other web-enabled services to run more smoothly on slower broadband connections. The payoff, naturally, is that your Dropbox folders will take longer to synchronize.

Deleted a file you wish you hadn’t? Dropbox hangs on to deleted files for 30 days. If you need to resurrect one, open up a web browser, log into and click Files in the sidebar, followed by “Deleted files”. Click the file you want to recover, then click the Restore button.

From here you can also select “Delete permanently” if you want to remove sensitive files for good.

If you want to make sure that the data can’t ever be recovered, you will want to clear the local Dropbox cache on your local computers, too: you can find it at “%HOMEPATH%\Dropbox\.dropbox.cache”.

As well as deleted files, Dropbox also keeps track of changed files, and you can roll back to a previous version of an uploaded file if you need to undo any updates. In Windows, right-click over a file in the regular files view and pick “Version History” from the menu to view older versions.

As with deleted files, Dropbox keeps track of things for 30 days, so if you’ve made several changes in that time you should see them all stacked up. If your most recent amendment was more than a month ago, though, that’s the only version you’ll see.

The Dropbox app for Android and iOS lets you browse and view your synchronised files from anywhere. You can also download files directly to your device, meaning you can view and edit them in whatever app you choose to use. If you have made changes, you can normally save your updated file back to Dropbox via the Share menu.

If you’re using an iPhone or iPad, you can also access your cloud files

TOP Save space by choosing which files to sync locally

MIDDLE You can limit both download and upload rates

BOTTOM Dropbox keeps your deleted files for 30 days, so it’s easy to restore

via iOS 11’s Files app. Simply tap Edit above the list of locations and toggle the switch beside Dropbox to add it. Tap Done, then tap on Dropbox, and authenticate by logging in through the Dropbox app.

Once you’re logged in, your Dropbox files will be visible (you can also view files in Google Drive, Box and iCloud). They’ll also sync to the Recents tab – so anything you’ve been editing on another computer will appear at the top of the list on your iOS device, allowing you to quickly pick up and carry on.

You probably already know that you can share files and folders in your Dropbox with other users via the right-click context menu. What you might not know is that you can also actively request files you don’t currently have access to. To do so, go to

Use Dropbox to develop a website

Dropbox can serve as a handy platform for web development, using a tool such as Wamp ( Wamp installs Apache, MySQL and PHP, and can be easily configured so that your default web folder is inside your Dropbox account. With this done, amendments made to the development site on one machine will then be automatically synchronised across each of the others.

To do this, you just need to create a new folder called “htdocs” in your Dropbox folder, then edit the “httpd- vhosts.conf” file in your Wamp installation. You’ll find this in “C:\wamp64\bin\apache\<your Apache version>\conf\ extra\”

Change all of the references on lines six and seven from “$(INSTALL_DIR}/www” to the path to the new htdocs folder on Dropbox.

You’ll also need to update your database. Open “my.ini” in the folder ”C:\wamp\bin\mysql\<your MySQL version>\” and redirect the datadir address to a new data folder on your Dropbox account into which you should copy the contents of the Wamp installation’s “data” folder.

and click “Request files”. Provide details of what you want to receive and choose a folder in which to save it, then either email the link that Dropbox generates or enter the email addresses of anyone who needs to send you files. None of the senders will be able to see anyone else’s submitted files, so it’s a great way to collect job applications or assignments. When the deadline’s passed, close off the request and disable any further submissions.


A simple but useful trick: normally when you share a link to a file on Dropbox, the generated link takes the recipient to a screen on which they need to click a second time before the file downloads. Save them a step by changing the “dl=0” on the end of the link to “dl=l”: this means that, when they click the link, the file will download immediately.

Your Dropbox may contain all sorts of personal and professional files: you might well want to protect them from prying eyes by adding an extra degree of security to your account. On the Dropbox mobile app, open the app settings, then tap Passcode lock, and supply a four-digit code: in future this code will be required in order to view the contents of your Dropbox. On some devices it’s possible to use a fingerprint instead.

You should also secure access to your account via the Dropbox site by enabling two-factor authentication. Open and click the switch beside two-step verification. Provide your existing password and choose whether you want to receive an authorization code via text message to confirm logins from new devices, or whether you’d prefer to use an authenticator app. If you’re happy to share your number, texts are usually the simplest solution.

The only catch with the text message approach is that if you don’t have your phone handy,

TOP You can restore previous versions of files going 30 days back

MIDDLE Secure your account by enabling two-step authentication

BOTTOM You can actively request files you don’t have access to

you won’t be able to receive an authentication code, so you won’t be able to login from a new device. To help you avoid this problem, Dropbox also provides a list of one-off backup codes that you should note down in a safe place.

If possible, try and memorise one of them, so you can always unlock your account even if you have nothing at all to hand.

Another worthwhile security measure is to unlink any devices that haven’t been used for a while from your account. That way, even if someone else is able to get into your old phone or laptop, they won’t be able to rifle through your Dropbox. To do this, go to the Dropbox website, click Security and review your linked devices. There’s no way to unlink all but the current device automatically, so you’ll need to go through the list of linked devices one by one, clicking the X beside each.

Similarly, there’s no reason to allow old apps that you’re no longer using to have continued access to your Dropbox. Click through to the Connected apps tab and make sure all of the applications you’ve granted access to over the years still really do need authorization to read, save to and delete from your account. Once again, click the X next to any that should be removed.

If you want to ensure that no-one else can access your cloud files, consider encrypting your uploads. One easy way to do this is with a tool called Boxcryptor (boxcryptor. com), which is free for personal use if you only want to synchronise between two devices and a single cloud provider – although around 20 providers are supported, including Dropbox, Google Drive and OneDrive. It runs on your PC or Mac (with mobile clients also available for Android and iOS) and creates a virtual Boxcryptor drive on your PC, which is connected to your Dropbox account but automatically encrypts files before

uploading them. This way, you can easily choose which files are encrypted and which are uploaded in their native formats, for sharing with others.

However, Boxcryptor isn’t the only encryption option: alternatives include Sookasa ( dropbox-security) and Encrypted Cloud (

You’re probably well aware of IFTTT (, the popular online automation tool. But did you know that it has dozens of pre-rolled recipes ready to use with Dropbox? These range from the fairly utilitarian, such as automatically copying Gmail attachments matching certain criteria to your cloud storage, to the more esoteric, such as saving trending GIFs from Giphy.

Our favourites include automatically posting all of the photos you drop in a particular Dropbox folder to Facebook, and backing up the images you save to 500px. There are also integrations for linking Dropbox to Slack, Gmail, Google Drive, Telegram, Flickr and dozens of other well-known services.

These pre-made workflows usually need just a single click to enable. You also need to give authorization to access your Dropbox account, and feed in a couple of simple variables such as your email address or Facebook login details. You’ll find the full list at

Although Microsoft Office 365 is tied to OneDrive, you can happily use it to work with files in your Dropbox. When you select an Office document in the Dropbox browser view, you’ll be prompted to authorise the Microsoft Office online apps to link to your account. The file will then open in the relevant app and, when you exit, the updated version will be saved back to your Dropbox account. If you’re using the desktop versions of the Office applications then Dropbox also adds useful collaborative capabilities (see right).

The Dropbox mobile app makes it easy to access your files while you’re out and about, but unlike the desktop client, it doesn’t actually sync files to your phone or tablet: all it does is provide links to download them on-the-fly when requested. This is fine until you hit a network blackspot. If you know you’re going to be travelling where coverage is patchy, tap the arrow beside each file you’re going to need and tap “Make Available Offline” to download a local copy. Local files will have a small green arrow icon. Check that any files you can’t do without have actually transferred by switching your device to Flight mode and tapping them in the Dropbox app.

Web hosting isn’t expensive, but the cheapest deals often come With limited storage and bandwidth.

As an alternative – if you’re not worried about having a custom domain name or using flashy interactive technologies such PHP or WordPress – it’s perfectly possible to host web pages in your Dropbox Public folder.

If you want to ensure that no-one else can access your cloud files, consider encrypting your uploads with a tool such as Boxcryptor

To do this, simply upload your HTML files into your Public folder, then copy and share the link with whoever needs access.

The important part is to remove “?dl=0” from the end of the URL, which makes sure that the page opens up in the browser rather than being downloaded onto the visitor’s machine.

If you want a memorable custom address, check out DropPages (, which will either give you a free subdomain (such as or allow you to redirect to your own domain for a few dollars a month.

Although the DropPages service doesn’t actually serve web content directly from your Dropbox account, you can still use it in exactly the same way: your uploaded files are automatically synced from your Dropbox Public folder to the DropPages server and served from there.

What is Dropbox Badge?

The smart sharing for Microsoft Office

Dropbox’s sharing capabilities aren’t just about behind- the-scenes syncing. If you’re running Dropbox for Business then the Dropbox Badge integrates directly into Microsoft Word, Excel and PowerPoint – you’ll see it attached to the right of the program window. At its simplest, this adds basic Dropbox services to your Office applications; you can click on it to copy a link to your document for sharing with others, view the file’s history on the Dropbox website – and optionally roll back to a previous state – and see who else can access it

Where things start getting clever is when two or more people are editing a file simultaneously. When someone else opens a file you have open, their picture and initials pop up, and Dropbox lets you know they’re editing it by showing a lock on a red background – a warning that saving your own edits may create a duplicate.

If the lock becomes an exclamation mark, you’ve both made changes. You can’t both make live updates to the same document, but when you save your work, Dropbox will warn your collaborator. Or, if they beat you to it and save before you do, you’ll see a download arrow instead, so you can save your changes as a separate file and download your colleague’s work. Your original will then show with a grey Dropbox badge.

You can turn the Dropbox badge on and off through the app’s Preferences pane; checkout for more information.
