I am not knowledgeable in networks, but the Organizer has not been devised for networks. You can do it at your own risks and perils, but you won't get much support.
As far as I have seen, many people have problems to let photoshop automatically watch for new contents in folders located on network drives.
I think only a very small part of Elements users are using networks, but most of them have problems.
As networks are become less rare in personal environments, I think Adobe should be clear about that restriction in the System Requirements.
Thanks for the quick reply!
The solution under the link you posted, just says "On the Logon tab, change to “This account” and enter the name of your account (on the computer that runs PSE) and its password". The problem is, that I am not sure what to enter as account and password when I change the logon information from "this account" to "this account" (german version: "dieses konto"). There is a button "search/browse" (german: "durchsuchen") with which I get into another menu allowing me to select objecttyp and path for the user which should be logged on, but objecttyps just lets me select "users" and the path only lets my select my desktop pc not the nas/network drive. I don't see any accounts here. There is a possibility to just enter the objecttyps to use, but I don't know what to enter. I am using my computer with the local user (administator access as far as I think) and no password. the network drive (QNAP, Unix) is accessed with user (different name as the local user I use for Windows) and a password. So do I have to enter name/password for the network drive or name/password for the computer? As active file monitor is a service running from the windows environment I think it can only refer to the Windows user. But that would be the same user as the local systemaccount which is the default user which already runs the active file monitor as I only have one windows user configured. Or is there a difference between local systemaccount and local user? But if you have to use local user or local systemaccount how does the system get the the login information for the network drive? Or are those stored with the local user (..different to the local systemaccount..) when I start up the computer?
Still lost... And yes, Adobe should find a better solution as more and more people are using network drives because of more and more tablets, cell phones and so on using the same data (if you don't want to use any cloud solution).
