Logs: To avoid QVWs writing reload logs, disable it in the Settings > Document Properties > Generate Logfiles
Shared: Disable all server object related properties in documents and QMC, so no user can create any object (not only charts, also bookmarks) and session recovery. Documents will open always with the layout and selections when the document was saved.
Meta: switch from DMS to NTFS. Be aware that permissions for QlikView applications must be set in Windows, you cannot use forms or SSO solutions in this case.
Then stop all QlikView services, remove the files and start them up again.
