How do I save space on my computer with Selective Sync?

Selective Sync is a feature of the Dropbox desktop application that allows you to select only the folders you want to be synced to your computer. Selective Sync gives you the control to ensure you have only the files you need on any computer. It's especially handy if you want to save space on netbooks and other computers with small hard drives.

From the command line

If you have the Dropbox command line instructions script, then all you need to do to add a folder to the Selective Sync "do not sync" list is enter the following command in your Terminal.

/path/to/dropbox.py exclude add ~/Dropbox/path/to/folder/

Simply substitute the /path/to/ to the actual paths to the CLI script and the folder or file, respectively.

What happens if my hard drive doesn't have enough space to sync all of my files?

When you save a file to Dropbox, it syncs with all of the devices you've connected with your Dropbox account. This means that it takes up space on each computer hard drive. This can create problems if your hard drive doesn't have enough available space to sync everything in your Dropbox.

If your hard drive is full, you don't necessarily need to delete files. If you have enough Dropbox space, you can instead use Selective Sync. See the instructions above for using selective sync.

Dropbox for Business: How does selective sync work with shared folders?

If you're a Dropbox for Business team member, you may be a member of large shared folders that you don't use. If your Dropbox folder becomes too large for your hard drive to handle, you don't necessarily need to delete these folders.

  • Note: Deleting files from a shared folder will delete the files for every member of that shared folder. However, if you delete the entire shared folder it will only be removed from your account.

To clear up your hard drive without affecting anyone else’s workflow, it is best to use Selective Sync. See the instructions above for using selective sync.

For our advanced users

Selective Sync conflicts

Folders that are deselected in Selective Sync preferences will be removed from the Dropbox folder on your hard drive. However, if a folder is created with the same name in the same place as the unsynced folder, the new folder will appear with a gray circle and a minus sign overlay. This icon indicates the folder is not being synced to your Dropbox. If you resume syncing your old folder of the same name through Selective Sync preferences, the new folder and its contents will appear alongside the old folder and have "Selective Sync conflict" in the folder name.

Leaving shared folders

Deselecting a shared folder from your Dropbox Selective Sync preferences will only prevent syncing to your computer. The shared folder will remain synced and active in the Dropbox of other members of the shared folder. To remove yourself from a shared folder, you can either leave the shared folder from the Dropbox website or, if you're the owner of a shared folder, you can unshare the folder.

Selective Sync unavailable while Dropbox is paused or indexing

If you're running the Dropbox desktop application for the first time, you may have to wait until Dropbox has finished indexing the files in your Dropbox folder before you can access Selective Sync settings. If you see a message that says "Performing initial sync with server. Please wait...," it means the Dropbox desktop application is in the process of indexing the files in your Dropbox or you have paused syncing from the Dropbox menu. You can choose to wait until indexing is complete to access your Selective Sync settings. Otherwise, select Cancel to dismiss the message and return to your preferences window. If you have paused syncing, you can resume syncing via the Dropbox menu.

Dropbox will continue indexing (as indicated by the blue icon with rotating arrows over your Dropbox icon) and you'll still be able to browse and change other preferences while Dropbox finishes.
