The Dropbox desktop app

What is the Dropbox desktop app?

The Dropbox desktop app lets you work with your files from a folder on your computer, inside File Explorer on Windows or Finder on Mac, so it feels familiar from the start. You can move, add, rename, or delete files just as you normally would. The app quietly syncs your changes to your Dropbox account and to your other devices in the background, keeping everything up to date. If you lose your connection, you can keep working with the files on your computer or the ones you’ve made available offline. When you’re back online, Dropbox picks up where it left off and updates your changes everywhere.

When you install the app, you’ll see two things on your computer:

• A Dropbox folder in File Explorer or Finder.

• A small Dropbox icon in your taskbar (Windows) or menu bar (Mac).

Use the folder for everyday work. Drag in files, organize folders, and open items like you always do, and Dropbox handles the syncing in the background. The icon is your quick status and control center. You can check recent activity, see whether files are up to date, pause syncing, or open Preferences.

Note: If you’re low on space, mark items online-only so they stay in Dropbox without using local storage, then switch them back to available offline when you need them on the device.

In short, the desktop app gives you access to your files across multiple devices, wherever you go. You get the simplicity of a normal folder, along with the confidence that everything is secure and up-to-date.

Installing the Dropbox desktop app

1. Go to dropbox.com/downloading.

2. Open the installer and follow the prompts.

3. Log in with your email and password, or select Continue with Google or Continue with Apple.

4. Look for the Dropbox folder on your computer and the Dropbox icon in your taskbar (Windows) or menu bar (Mac).

5. Add files to your Dropbox folder to sync them to your account and other devices.

But what is syncing?

Syncing is how Dropbox keeps the same file up to date in more than one place.

Imagine you have a to-do list in a special folder on your laptop. The same list also lives in your Dropbox account on the internet. When you add a new task or check something off on your laptop, Dropbox notices the change, updates the copy online, and then updates it on your other devices too, such as your phone or another computer.

You don’t have to copy the list by hand or email it to yourself. You just save it in your Dropbox folder, and syncing makes sure that:

• The latest version is saved to your Dropbox account.

• The same version is available on your other devices when they are online.

Selective sync

Selective sync lets you choose entire folders to keep off a specific computer. This way, the folders stay in your Dropbox account without taking up local space.

Imagine you use a lightweight laptop with limited storage for meetings and travel, and a larger computer at home.

Your Dropbox has a few folders you use every day and others you only need from time to time. Selective sync lets you keep active folders stored on your laptop for quick access, while older or larger folders stay only in your Dropbox account to save space. You can still open those folders on dropbox.com or another computer, and you can turn them back on for this laptop any time a project becomes active again.

Selective sync helps in shared folders as well. If a team space includes a large “Assets” folder that you rarely touch, you can deselect it on your laptop to save space and reduce clutter, while teammates who rely on those files keep the folder on their devices. Your choices apply only to that computer, nothing is deleted from Dropbox, and you can change the selection any time.

How to use Dropbox to save hard drive space with online-only files

Online-only keeps a file or folder in your Dropbox account without storing the full contents on your computer. You still see the item in your Dropbox folder, with a cloud icon, and you can open it when you need it. Available offline stores a local copy on your computer so it opens instantly without internet and stays up to date in the background.

You’re a freelance designer working on a single computer for a new client brand refresh. To keep your workspace tidy, you set the big reference folders - stock photos, raw exports, and old rounds online-only so they live in your Dropbox account without taking up space or cluttering your day-to-day view. You keep the current brief, the logo files you’re editing, and the presentation you’ll share this week available offline so they open instantly and stay up to date while you work.

As the project moves through stages, you can switch items one by one. After you deliver the first draft, you make the old explorations folder online-only and set the finals folder available offline while you polish changes. If you need a reference file, you open it from the online-only folder, Dropbox downloads it for use, and you can return it to online-only when you’re done. This way, your active work stays close at hand, and everything else remains one step away in the same place.

How to make files online-only by default

To make all files that you add to the Dropbox folder on your computer online-only by default:

1. Click the Dropbox icon in your taskbar (Windows) or menu bar (Mac).

2. Click your avatar (profile picture or initials) in the bottom-left corner.

3. Click Preferences.

4. Click the Sync tab.

5. Click the dropdown next to New files default.

6. Select Online-only.

All future files and folders added to your Dropbox folder will be online only. New files added won’t take up storage space on your computer once they’ve been added, however these conditions don’t apply to files or folders that already exist.

Free up space on your computer

To free up room on your device, set files or folders to Make online-only from the context menu in your Dropbox folder. The item stays in your Dropbox account and no longer uses local storage. When you need it again, switch it back to Make available offline to download a local copy. If you want to hide entire folders from this computer, click the Dropbox icon in your system tray or menu bar, select your avatar, click Preferences, then click Sync, and use Selective sync to deselect folders you do not need on this device.

Manage your Dropbox storage

Start by removing large files you no longer need, either by moving them out of Dropbox or deleting them if you are finished. Review shared folders and leave the ones you do not use, or ask the owner to share only the parts you need. For long-term archives, save copies to external storage, confirm they are backed up, and then remove the versions in Dropbox if you no longer need them there.

What is File Provider on Mac?

If you use Dropbox on a Mac, you might notice that your Dropbox folder appears under Locations in Finder, some files show a small cloud icon, and everything feels more built in to macOS. This experience is powered by a feature from Apple called File Provider.

File Provider is a macOS framework that lets apps such as Dropbox show cloud files in Finder as if they were on your Mac, while still keeping them in sync with online storage. Dropbox uses this newer File Provider technology so that:

• Your Dropbox folder appears in a standard place in Finder, under Locations.

• Online-only files show with a cloud icon, so you can see which items are stored in the cloud and which are available offline on your Mac.

• macOS can help manage disk space by keeping rarely used files online-only, while you keep important folders always available offline.

From your point of view, the basics you learned about sync stay the same. You still see a Dropbox folder in Finder, you can still open, move, and rename files, and changes still sync between your Mac and your Dropbox account.

File Provider is recommended for the best experience on macOS, however it is not required in order to keep using the Dropbox desktop app. If your Mac or account has not been updated to the new experience yet, Dropbox will continue to work with the existing desktop app and the sync features you already learned about.

Your files still sync. You can choose which items are available offline or online-only, use Selective sync where it’s available, and keep working from the Dropbox folder on your Mac just like before.

Troubleshooting

If the desktop app has stopped syncing, the number of files syncing seems to be “stuck,” or updates are not appearing across your devices, the cause is usually a connection or settings issue. If you are working with very large files or a slow network, check your connection speed, pause other bandwidth-heavy activity, or connect to a faster, reliable network, then check sync status again. If things still do not move, these quick checks often get syncing back on track.

• Make sure you are online, and review any firewall, security, antivirus, or network restrictions that could block Dropbox. Also confirm your device date and time are correct.

• Keep the Dropbox desktop app open so new files can finish syncing.

• Check your sync status, and confirm Selective sync has not removed the folder from this device.

• If an item is online-only, open it to download or set it to Make available offline.

• Confirm you have enough storage quota, and check file size limits (very large files or long folder paths can hit limits and fail to sync).

• Check for special characters or unsupported file types that can prevent syncing (for example, characters your operating system does not allow, or file types listed in the Dropbox Help Center article on upload limitations).

In this module, you’ve seen how the desktop app fits into Finder or File Explorer, how syncing behaves, and how tools like selective sync and online only files help you manage space. In the next module, you’ll learn how to create folders, upload files, and bring new content into Dropbox from different devices.
