## How package priority is determined
The virtual environment and its current state are associated with the connection group, not with the individual packages. If you remove an App-V package from the connection group, the state that existed as part of the connection group will not migrate with the package.
The virtual environment and its current state are associated with the connection group, not with the individual packages. If you remove an App-V package from the connection group, the state that existed as part of the connection group won't migrate with the package.
If the same package is a part of two different connection groups, you have to indicate which connection group App-V should use. For example, you might have two packages in a connection group that each define the same registry DWORD value.

The connection group that is used is based on the order in which a package appears inside the **AppConnectionGroup** XML document:

Assume that same DWORD value ABC (HKEY\_LOCAL\_MACHINE\\software\\contoso\\finapp\\region) is defined in the first and third package.
For this example, the DWORD value definition would be the following:
For this example, the DWORD value definition would be as shown below:
- Package 1 (A8731008-4523-4713-83A4-CD1363907160): HKEY\_LOCAL\_MACHINE\\software\\contoso\\finapp\\region=5
- Package 3 (04220DCA-EE77-42BE-A9F5-96FD8E8593F2): HKEY\_LOCAL\_MACHINE\\software\\contoso\\finapp\\region=10
Since Package 1 appears first, the AppConnectionGroup's virtual environment will have the single DWORD value of 5 (HKEY\_LOCAL\_MACHINE\\software\\contoso\\finapp\\region=5). This means that the virtual applications in Package 1, Package 2, and Package 3 will all see the value 5 when they query for HKEY\_LOCAL\_MACHINE\\software\\contoso\\finapp\\region.

Other virtual environment resources are resolved in a similar way, but usually collisions occur in the registry.

When a virtualized application tries to find a specific file, App-V will first for a matching file path in Package A. If it doesn't find a matching path in Package A, it will then search Package B using the following mapping rules:
When a virtualized application tries to find a specific file, App-V will search for a matching file path in Package A. If it doesn't find a matching path in Package A, it will then search Package B using the following mapping rules:
- If a file named **test.txt** exists in the same virtual folder hierarchy in both application packages, App-V will use the first matching file.
- If a file named **bar.txt** exists in the virtual folder hierarchy of one application package, but not in the other, App-V will use the first matching file.
