Best practice is probably avoid using quick User switching all, rather log out of one user before logging into another one, but at a minimum, even if you do quick switch, don’t leave Picasa open in two user accounts at the same time. we’re actually very close, the logic is surprisingly simple: map the drive that has our Picasa library and databases as a network drive, say P, then apply the tricks we’ve just learned doing the multi-user setup on the same computer, but now the symbolic links will point to the public folders on the P: drive, and voila!Well, almost…too bad there are a number of quirks that we have to deal with first. If you have a NAS drive, which is for passive storage only, accessed by several computers on the network, than the above solution will work, since you can map the NAS drive to the same drive letter on all computers. there is no NAS, Picasa resides on one of the actively used computers which all others access, then you run into all sorts of trouble.Picasa’s does not accept a \Computername\Foldername designation, it has to look all local. Oh, well, we’ll outsmart the system again, by combining network mapping with symbolic linking: we’ll map the network drive to an interim name first, then link to this interim drive-name.Steps: Repeat the last three steps for all user accounts that should access Picasa from this computer.Ideally we would just map the public drive on the server as a network drive under P: but we’ll run into a syntax problem.On the main computer Picasa will prefix our watched folder setting, changes \P\Pictures to C:\P\Pictures, which works just fine on the main computer but not on the satellite ones. But now even this old friend lets us down: we cannot define a symbolic link to a network folder, only a local one.The problem is, the “main” computer will consider Picasa storage as its C: drive, while all others have to refer to it by another drive letter, since C: is reserved for their own hard disk.
but wait, first things first: Picasa is my favorite photo management program, and hey, it’s hard to beat free!Yes, there is one – keep on reading :-) But first some disclaimers: Now, we’re ready to rock and roll …You may only be interested in the multi-computer setup, but please read this chapter anyway, as we will build on the logic outlined here when we expand to a network setup.If you use nested folders, you’re in luck, you can just right click on the top-level folder, select “Move Folder”, pick the new destination, and you’re done.(If you have nested folders but don’t see them in Picasa, change from “Flat View” to “Tree View” in the main View menu.) If you have a lot of flat folders, this may be a cumbersome process, but it’s one-time only. now close Picasa and let’s get really started :-) Two reminders before we start: \App Data\Local\Google\ folder – if you do, you likely copied them to the new destination instead of moving.In the meantime wireless home networks became more robust, so instead of redundant chaos, the next best option was maintaining once central Picasa home-base, and accessing it from other computers via the network.
