Do shared folders count against my storage space?

Shared folders use space in each member’s account unless each person is on the same Dropbox team.
 

Your Dropbox storage quota is calculated by adding up the total amount of data in your Dropbox account. This includes all shared folders you're a member of and all files collected from file requests.

What happens if someone shares a folder that’s larger than the amount of space you have left?

If someone shares a folder with you that's larger than the amount of space you have left, you won’t be able to join the folder.

For example, if you have a Dropbox Basic 2 GB account, and you’ve used 1.5 GB of space, you can’t accept a shared folder larger than 0.5 GB. 
 

Can I view shared files that are larger than the remaining space in my account?

If you need to view shared files that are larger than the remaining space in your account, you can:

• Ask the person who invited you to send a shared link to the folder instead
• Upgrade to Dropbox Plus or Professional

How do shared links affect my storage space?

Links that have been shared with you don’t take up space in your account, and you can download those files to your computer.

If you download a file from a shared link, you can edit your downloaded copy. However, your edits won’t sync with the original file that was shared with you.
 

Do shared folders affect my storage space if I’m a Dropbox team member?

If you’re a member of a Dropbox team, the size of a shared folder only counts once against the entire team's shared quota.
