Section 4 - Configuration
Space Used This shows the currently used space and the total quota of
your Dropbox account.
Note: When you do not have enough space in your Dropbox
account or local volume, the application will stop syncing
until free space is available. Syncing will restart afterward.
Sync Interval You can set how often to sync changes from the Dropbox
side by selecting "Hourly", "Daily", or "Weekly" here. Click "Save
Settings" to apply.
Note: The changes on your local sync folder will be queued
immediately, so sync interval will not apply to this process.
Last Update This shows when the last activity or Dropbox sync was done.
