Libraries and Homegroups: New Ways to Organize and Share

Something Microsoft has been trying to conquer for some time is home file sharing, with limited results. Vista added an easy way to turn on network sharing of the Public folder, but this was a limited utility solution that was only helpful in sharing items specifically placed there, and other users still needed to go hunt down the network share (which brought plenty of problems of its own). Network shares are inherently a client-server design, while for home file sharing you need something closer to a peer-to-peer design.

With Windows 7 Microsoft appears to have finally gotten this right with the addition of two new features; Homegroups and Libraries. Homegroups are in essence auto-configuring network shares designed to act like a peer-to-peer network. When the first Windows 7 machine is added to a network, the user can choose to create a Homegroup along with what libraries they wish to share. Any libraries they choose to share will be opened up with read-only access to everyone else in the Homegroup, with Homegroup access limited by a shared alphanumeric password created along with the Homegroup.


Homegroup Configuration

Sitting on top of the Homegroup is the Windows 7 Libraries feature. Libraries in this case are a kind of meta-folder for various types of files, listing the contents of several different locations as if they were all in the same local folder. In turn Windows treats a library as a local folder and includes all the contents of a library in a regular search, or when browsing through files on Windows Media Player/Center, etc. Windows 7 comes with four libraries by default: Documents, Music, Videos, and Pictures. As there’s nothing special about a library other than where they search, any number of additional libraries may be created and shared.


Viewing the Music Library

The ultimate purpose for libraries is that they basically allow for the transparent integration of network shares, and this in turn is what makes Homegroups work. Once a computer has joined a Homegroup, its shared libraries become available as additional libraries, making the use of shared files largely transparent. In turn these remote libraries can be added to the local libraries, making the process fully transparent. Libraries can also be manually adjusted, allowing for files in other locations (local and remote) to be added to a library, although only local material is shared with a Homegroup. For the same reasons, this also solves the integration issues of Windows Home Server – Home Server shares can be added to a library, and made equally transparent.


Configuring A Library

It should also be noted that the meta-folder concept of libraries works in reverse too. Besides bringing together files from multiple locations, it’s a valid (and default) place to save files. In this case every library has a single defined “default save location” where all documents saved to that library actually get written to. By default, these locations are the regular folders inside of the user’s home directory.

In households with multiple computers, we’d expect that Homegroups turn out to be one of Windows 7’s most popular features given how easily we were able to set a group up and how well it worked in our testing. Libraries may be a hard sale however for users without multiple computers due to inertia, even if they’re still extremely useful for local-only use. We’ll have to see how this plays out.

    I have the W7 Beta, and it wouldn't install off of a SATA Optical Drive onto a PATA HDD.

    Weirdest problem I have ever seen, couldn't even see the Optical drive once 'windows' the (pre-installation environment) had loaded.

    I guess I needed to load RAID drivers? Seems annoying to let it boot the install without drivers, and then hang when attempting the install off media it just booted from.

    It isn't "Terrible", but it ain't quick neither. I hope it gets better, but it still doesn't have the lean and mean feel of a good fresh 2000 SP4 install, or even XP SP2/3. (dual core 2.4Ghz 2GB DDR2-800 8600GTS)

    Maybe I need an SSD?

    Random question from an XP user. ;)

    I mostly like RC1. I was able to customize the UI enough to be mostly satisfied with it, except for one setting.

    In XP, when you navigate the Start menu folders, the different folders cascade from left to right. Example: Start > Programs > System Tools > Backup. You know the drill.

    In RC1, each folder overlaps the previous, and you have to use forward/back buttons to backtrack. I find this annoying actually. I prefer XP's workflow. Is there a setting where I can make the folders function like XP?

    Thanks for the excellent article guys, covered practically everything I wanted to know about the RC before taking the plunge myself and formatting my hard drive for the install.

    Cheers!

    "Multiple GDI applications can now issue commands to it at the same time, and this is all pushed off to the video card to be its problem."

    I'm pretty sure this means that alt-tabing from a game to desktop will be quicker. :)

    It's all good, but Windows XP x64 is not an XP. It is based on Win 2003 Server core and share's the same updates (so there is no Win XP x64 SP3)
    It doesn't reflect the real XP performance and it's not that good from compatibility view. The most common OS switch would probably be Win XP x32 -> Vista x32/64 ?-> Win7 646432/64

    Anyone know how to get hardware accelerated video decoding in windows 7. I've gone through a couple guides with no luck so far.

    Seriously, fuck off with the apple loving bullshit. Mac os isnt competing against Microsoft, if they did they would have their asses handed to them by the mass public complaining nothing works. They build their os for a specific set of hardware.. thats like making a fucking Operating system for a console. Until they have the balls to step out and compete against Microsoft in the OS department and drop their over priced proprietary bullshit then they can fucking burn down for all I care. So stop putting them on the table like they even matter. Its been 5 minutes you better go fucking check to see if steve jobs is in the hospital again hadnt you bitch ?

    You're late - the people claiming Anandtech has a MS bias got in on the first few pages of comments.
  • Lexington02 - Wednesday, May 6, 2009 - link

    He is not late, he is claiming otherwise to the other people who think that Anandtech is MS loving while this dude is claiming to be Apple loving. I wonder, which is true... Apple lovers or Microsoft lovers...
