Tracking ID 699-70: Blocked Documents Added to Zip Files in Sync Folders Cause Entire Zip File to Be Deleted

The Client File System Agent (CFSA) can delete zip files stored on targets such as removable devices, network folders, or in file sync folders.

If a user attempts to add an unauthorized document to a zip file in a target location monitored by the CFSA, the CFSA blocks the document but also deletes the entire zip file. This happens even if the zip file contains other benign documents that do not breach policy.

If you use the CFSA to protect files copied, we recommend that your users refrain from storing zip files in target locations monitored by the CFSA.

Note: This issue also affects compressed folders created in sync folders on Windows 8 and Windows Server 2012 machines. These compressed folders are actually rebadged zip files.
