The plugin uses the cloud provider's API directly, so any limits that apply are the cloud provider's, not ours. In normal use this is rarely something you need to worry about.
Two kinds of limits to be aware of
1. API request quotas (rate limits)
Each cloud provider caps how often the plugin can talk to their API per second, minute, or day. Heavy traffic, very large folder structures, or many simultaneous visitors can push you against these caps. When that happens the plugin retries automatically and recovers in most cases.
Current rate limits per provider:
- Google Drive API limits
- Microsoft Graph throttling (OneDrive and SharePoint)
- Dropbox API rate limits
- Box API rate limits
2. Storage and outbound-traffic quotas on your cloud account
Your cloud account has a finite amount of storage and, on some plans, a cap on outbound traffic from shared links or downloads. These limits are set by your subscription with the cloud provider, not by the plugin.
If you hit one of these caps, the plugin returns the error message the provider sends back. The fix is on the cloud provider side: upgrade your plan, free up storage, or wait for the quota window to reset.
Limits change over time and per plan, so we don't reproduce specific numbers here. Check your provider's pricing or admin documentation for current values.
What about server bandwidth on your hosting?
Files normally stream directly from the cloud provider to the visitor's browser, so they don't pass through your web server. See Does the plugin use my hosting bandwidth? for the few exceptions.
