Microsoft recently rolled out a newWindows 10build to Fast Ring Insiders. So, if you already got bored with the previous build, you can now install build 17604.

This new release adds a very interesting feature to the table, namely theWindowsProjected File System.

Insiderscan already enable this feature by going toWindowsFeatures > TurnWindowsfeatures on and off. All you need to do is check theWindowsProjected File Systembox and that’s it.

Tero Alhonen also noticed this change and shared the screenshot above with the whole world on Twitter.

On the other hand,Walking Catsuggests that Microsoft renamed the GVFS (Git Virtual File System) to ProjF (WindowsProjected Filesystem).

Anyway, we’ll dig more into this and update the article as soon as new information is available.

So, if you installed the latestWindows 10build on your computer and tested theWindowsProjected File System feature, tell us more about your experience in the comments below.

UPDATE:

As one of our readers explained, instead of having developers install GVFS, the Redmond giant is now including it as a feature ofWindows. This corroborates Walking Cat’s hypothesis.

WindowsProjected File System is not security-related asWindowsSecurity is focusing on Virtualization-Based Security.WindowsProjected Filesystem is likely similar to what they did with OneDrive: the files are on a remote server, and you can see “placeholders”, but they’re not actually on your machine unless you open them (thus a “projected” file system).UPDATE: Just checked someWindows Insiderand other developers’ Twitter accounts, andWindowsProjected File System is what powers GVFS, allowing for very large repositories with little performance impact. It is marked “Beta” because there is no documentation yet.
