The QlikView Server Root folder maintains the softwares operational files (.pgo) and will be default be stored in C:\ProgramData\QlikTech\Documents. This can be modified.
We recommend not storing Qlikview Applications (.qvw) or other files such as script files and .qvds in the same location.
The Root Folder and .pgo files can be easily moved by configuring a new location in the QlikView Management Console. Before moving, ensure that the Service Account of the QlikView services has the correct permissions on the destination, and that the drive used is supported by Qlik. See Shared Network Storage
found on the Qlik Help for your respective version, as well as Does QlikView Support NAS Storage?
In the QlikView Management Console navigate to System
and make the required changes.
Once the new destination has been selected and applied, all .pgo files will be created in the new root folder. A restart of the Qlikview Server Services will be done automatically.
