This behaviour may be triggered by Windows Explorer Shell Extensions added by some applications.
When the right-click context menu is opened, some applications' shell extension may request the full content stream associated with the Placeholder.
File System Archiving cannot control or prevent this behaviour.
For customers who require the relevant Applications that add shell extensions to Windows Explorer, an alternative recall method can be configured using the PassThrough feature in FSA.
For more information on implementing PassThrough, please refer to the Enterprise Vault official product documentation.
The 'Setting_up_File_System_Archiving', both .pdf and .chm versions, cover the configuration steps in detail.
