Distributed File Systems (DFS) are not supported by QlikView. This includes the storage of .qvw files, .qvd files, .pgo files, .shared/.tshared files or other operational files and executables.
Distributed File System (DFS) is a set of client and server services that allow an organisation using Microsoft Windows servers to organize many distributed SMB file shares into a distributed file system.
DFS provides location transparency (via the namespace component) and redundancy (via the file replication component) to improve data availability in the face of failure or heavy load by allowing shares in multiple different locations to be logically grouped under one folder, or DFS root.

Due the nature of such distributed, possibly replicated file shares, we are not able to support them for a usage with QlikView. Meaning, that if such a DFS file share is used to store QVWs or PGOs, etc. on, we expect problems in storing or accessing those.
