App-V 5 Sequencer Template – Full VFS Write Mode

With the recent release of Hotfix 4 for App-V 5.0, Microsoft has now provided the ability to “Allow virtual applications full write permissions to the virtual file system”. This setting can be found in the sequencer under the “Advanced” tab as demonstrated in the screen shot below:

 Sequncer Full VFS

Should you wish to enable this setting as a default whenever you create a new package, then simply go ahead and add <FullVFSWriteMode>true<FullVFSWriteMode> into your sequencer template (.appvt), as you can see below. This setting is only valid where you have the App-V 5.0 SP2 Hotfix 4 sequencer installed.

And if you’re not currently using a template then I’d highly recommend you do. You’ll find a great article over at Rory Monaghan’s blog that explains the use of the sequencer template in more detail.

    The client must also be upgraded to HF4 to take advantage of writing in vfs?

    Hi Nick,

    Yes that is correct the client also needs HF4 applied.

    Code seems little but most useful, just looking for this…

    Is there a way to apply this template when converting Appv 4.x packages to Appv 5 using ConvertFrom-AppvLegacyPackage? I am primarily interested in the full write mode, so if the template cannot be applied, is there another way to do it?

    Hi Paul,

    Unfortunately you can’t specify a template when you perform the conversion. You’ll have to convert the package, “Edit” it in the sequencer and select the full write option in the “Advanced” tab and save the package.

    The VFS full write mode is actually specified in the AppxManifest.xml, which is created and complied into the .appv when you create the sequence – but again there is no official why to edit that file on the fly. Having said that you could use AVE from that will enable you to set the VFS full write mode using the GUI, much like you can do in the sequencer.

    What is the default location of .appvt file so that when the sequencer is launched first time it reads the information from there ?
    Just like previously it was .sprt file was residing under resources folder.

    Hi Suraj,

    It doesn’t work like that in the App-V 5.x sequencer. If you wish to use a template, you’ll always have to select “File > Load Template” and browse for the template before you start sequencing. Therefore the .appvt file can reside anywhere (local drive or network share).

    Hello Nathan

    Thank you for prompt reply and providing valuable confirmation.

    Hi Nathan

    I have some more questions on App-v topics , so do you have any other blog where I can post those ? Or I can post here also ?

    It would be very useful if you could provide me answer of those.


  12. Nathan Sperry on April 14, 2016 at 08:57

    Hi Suraji,

    The best place to ask any App-V related questions would be on the Microsoft App-V Forum, which can be found here
