Environment
Micro Focus Filr 4.1.2
Situation
The Filr desktop client can unpredictably delete files from Net Folder(s) during synchronization of files which have been flagged "Make Available Offline".
Resolution
Fix:
Apply the 4.2 Filr Client which was made available in April 2020.
Workaround:
To prevent additional file deletions, disable desktop application access for the affected user(s), and allow them to work only via the web client. This setting is in port 8443 Administration Console > Management > Users > (select user(s)) > More > Desktop Application Settings. Click the "Use user settings to allow the desktop application to:" radio button, and deselect "Access Filr".
