I’m running out of disk space

If you see a low disk space error, it's possible that Dropbox can't sync files to your computer because your computer's hard drive is full.

How to tell if you’re out of disk space or Dropbox storage space

If you see the error "Your startup disk is almost full.” on Mac or “You are running out of disk space on [Drive name].” on Windows, then your computer is low on hard drive space.

If you see the error “Your Dropbox is full.” then your Dropbox account is out of storage space.

How to check your available hard drive space

To check your available hard drive space on a Mac computer:

  1. Open up a Finder window.
  2. Press Cmd+Shift+C.
  3. Right-click on the hard drive icon and select Get Info.The pop-up window will show you the capacity of the drive and the amount of space available.

To check your available hard drive space on a Windows computer:

Open Computer, where you should see how much free space you have left. If it does not, right-click on your hard drive and select Properties from the menu.

How Dropbox storage space works with your hard drive space

For Dropbox to sync completely, you need at least the same amount of hard drive space free as the amount of data in your Dropbox account. If you're trying to move files into your Dropbox folder from an external hard drive, you'll need to make sure you have enough space on your Dropbox account as well as your computer's hard drive to do so.

Dropbox will sync files to the Dropbox folder on your hard drive until it reaches capacity. Once your hard drive is full, you'll have to make room on your hard drive to sync more files. Even if your hard drive is full, your files are always available for access from the dropbox.com.

If you find yourself with a hard drive smaller than your Dropbox account, or you'd like to free up space on your computer, you can choose which files to sync to your computer via selective sync. Your Selective Sync settings can be found in the Dropbox desktop app settings.
