Currently, if I change setups then I have to change or import to each workstation rather than updating a shared file on a server.
I don't see a way to SAVE AS where you can choose you destination folder.
So if it was very important to me, I would write a very small 2 line batch file, which with a click will COPY from C:\Programdata\ddisoftware\qimage\save folder to the server folder. You can use the *.prt and *.prn as filters so you will only copy printer setups.
Another way is to use the Migrate data feature found under the Utilities menu called MIGRATE
That will move all the data to your chosen destination. Then it asks you if you want QU to use this new location, or continue using old location and you only wanted a backup copy.
One of these solutions should work for you.
The MIGRATE option is the cleanest and seems to sound like it is what you want.
