In this new “mini-series” I will take a close look into a Virtual Filesystem (VFS) feature found in App-V, and some of the things that I feel should be understood by everyone doing VFS sequences and especially when trying to troubleshoot them.

Having been inspired by a recent blog posting by Tim Mangan about currently known issues in package branching (and my own previous experiences of the same), both in 4.6 and 4.6 SP1 versions of the App-V Sequencer, I thought about to write a quick and short howto for doing branching operating with our Application Virtualization Explorer (AVE).

In this article, I want to give a brief lesson on something called OSD scripting. OSD scripting is a way to add dynamic or added functional behavior into App-V packages outside what the App-V itself as a virtualization technology provides.
