Overview

As an administrator, you can restrict file types from being synchronized to the server using policy settings. Specifically, the Excluded Extensions policy lists default excluded extensions that can optionally be modified to accommodate the needs of an organization. Using this policy, you can help protect organizations and user accounts from files that might contain malicious code. Other file types, such as temporary and system files and folders, are permanently blocked from the system (hard-coded).

This article will provide information on hard-coded excluded directories and extensions, as well as default excluded extensions that are configurable through policies.
