Your Dropbox storage space is calculated based on the space used by the total contents of your Dropbox account. Depending on your Dropbox plan, you’ll have a certain quota of space in your account. Once you reach this quota limit, syncing stops and you can’t add or make changes to files in your Dropbox account.
The space used by your account includes:
- Files
- Folders
- Shared folders
- Paper docs
The following types of files aren’t included in your space calculation:
- File versions
- Deleted files
