> **Important:**  Before setting up auditing for files and folders, you must enable [object access auditing](basic-audit-object-access.md) by defining auditing policy settings for the object access event category. If you do not enable object access auditing, you will receive an error message when you set up auditing for files and folders, and no files or folders will be audited.

## Additional considerations
- After object access auditing is enabled, view the security log in Event Viewer to review the results of your changes.
- After you turn on object access auditing, view the security log in Event Viewer to review the results of your changes.
- You can set up file and folder auditing only on NTFS drives.
- Because the security log is limited in size, select the files and folders to be audited carefully. Also, consider the amount of disk space that you want to devote to the security log. The maximum size for the security log is defined in Event Viewer.

This topic for the IT professional describes how to monitor changes to the central access policies that are associated with files and folders when you are using advanced security auditing options to monitor dynamic access control objects.
This article for IT professionals describes how to monitor changes to the central access policies that are associated with files and folders when you're using advanced security auditing options to monitor dynamic access control objects.
This security audit policy and the event that it records are generated when the central access policy that is associated with a file or folder is changed. This security audit policy is useful when an administrator wants to monitor potential changes on some, but not all, files and folders on a file server.
This security audit policy and the event that it records are generated when the central access policy that's associated with a file or folder is changed. This security audit policy is useful when an administrator wants to monitor potential changes on some, but not all, files and folders on a file server.
For info about monitoring potential central access policy changes for an entire file server, see [Monitor the central access policies that apply on a file server](monitor-the-central-access-policies-that-apply-on-a-file-server.md).
For information about monitoring potential central access policy changes for an entire file server, see [Monitor the central access policies that apply on a file server](monitor-the-central-access-policies-that-apply-on-a-file-server.md).
Use the following procedures to configure settings to monitor central access policies that are associated with files. These procedures assume that you have configured and deployed Dynamic Access Control in your network. For more information about how to configure and deploy Dynamic Access Control, see [Dynamic Access Control: Scenario Overview](https://technet.microsoft.com/library/hh831717.aspx).
