I would advise against it, because the availability of network folders are subject to network stability and load. Also, don't forget that your documents must reside on Windows machines.
If you don't mind the reduced loading/saving I/O speed, then you can open/mount a network folder just by clicking the green plus button, and in the Choose Folder dialog, select "My network places". There you'll get a list with available servers on your network.
Mounted network folders should always be specified using UNC paths, which start with a server name. That's why "My network places" should be the starting point.
If you don't find your server in the "My network places" server list, make sure that the service account that is running the QlikView services has access to your server with QlikView documents.
Both the machines in which application is copied and in which QMC is installed have to be in same network.
If you have publisher the path has to be changed in QMC--> System--> Setup--> Distribution service --> Source Documents. you can simply give \\IP Address\Folder.
If you have only Qlikview server license the path has to be changed in QMC--> System--> Setup-->
Qlikview Servers -> Root Folder \\IP Address\Folder
Hope this helps.
